DESCRIPTION
Awk Traps
C/C++ Traps
Sed Traps
Shell Traps
Perl Traps
Perl4 to Perl5 Traps
Discontinuance, Deprecation, and BugFix traps, Pars-
ing Traps, Numerical Traps, General data type traps,
Context Traps - scalar, list contexts, Precedence
Traps, General Regular Expression Traps using s///,
etc, Subroutine, Signal, Sorting Traps, OS Traps,
DBM Traps, Unclassified Traps
Discontinuance, Deprecation, and BugFix traps
Symbols starting with "_" no longer forced into
main, Double-colon valid package separator in vari-
able name, 2nd and 3rd args to "splice()" are now in
scalar context, Can't do "goto" into a block that is
optimized away, Can't use whitespace as variable
name or quote delimiter, "while/if BLOCK BLOCK"
gone, "**" binds tighter than unary minus, "foreach"
changed when iterating over a list, "split" with no
args behavior changed, -e behavior fixed, "push"
returns number of elements in resulting list, Some
error messages differ, "split()" honors subroutine
args, Bugs removed
Parsing Traps
Space between . and = triggers syntax error, Better
parsing in perl 5, Function parsing, String interpo-
lation of $#array differs, Perl guesses on "map",
perl v5.8.8 2006-06-30 6
PERLTOC(1) Perl Programmers Reference Guide PERLTOC(1)
"grep" followed by "{" if it starts BLOCK or hash
ref
Numerical Traps
Formatted output and significant digits, Auto-
increment operator over signed int limit deleted,
Assignment of return values from numeric equality
tests doesn't work, Bitwise string ops
General data type traps
Negative array subscripts now count from the end of
array, Setting $#array lower now discards array ele-
ments, Hashes get defined before use, Glob assign-
ment from localized variable to variable, Assigning
"undef" to glob, Changes in unary negation (of
strings), Modifying of constants prohibited,
"defined $var" behavior changed, Variable Suicide
Context Traps - scalar, list contexts
Elements of argument lists for formats evaluated in
list context, "caller()" returns false value in
scalar context if no caller present, Comma operator
in scalar context gives scalar context to args,
"sprintf()" prototyped as "($;@)"
Precedence Traps
LHS vs. RHS of any assignment operator, Semantic
errors introduced due to precedence, Precedence of
assignment operators same as the precedence of
assignment, "open" requires parentheses around
filehandle, $: precedence over $:: gone, Precedence
of file test operators documented, "keys", "each",
"values" are regular named unary operators
General Regular Expression Traps using s///, etc.
"s'$lhs'$rhs'" interpolates on either side, "m//g"
attaches its state to the searched string, "m//o"
used within an anonymous sub, $+ isn't set to whole
match, Substitution now returns null string if it
fails, "s`lhs`rhs`" is now a normal substitution,
Stricter parsing of variables in regular expres-
sions, "m?x?" matches only once, Failed matches
don't reset the match variables
Subroutine, Signal, Sorting Traps
Barewords that used to look like strings look like
subroutine calls, Reverse is no longer allowed as
the name of a sort subroutine, "warn()" won't let
you specify a filehandle
OS Traps
SysV resets signal handler correctly, SysV "seek()"
perl v5.8.8 2006-06-30 7
PERLTOC(1) Perl Programmers Reference Guide PERLTOC(1)
appends correctly
Interpolation Traps
"@" always interpolates an array in double-quotish
strings, Double-quoted strings may no longer end
with an unescaped $, Arbitrary expressions are
evaluated inside braces within double quotes, $$x
now tries to dereference $x, Creation of hashes on
the fly with "eval "EXPR"" requires protection, Bugs
in earlier perl versions, Array and hash brackets
during interpolation, Interpolation of
"\$$foo{bar}", "qq()" string passed to "eval" will
not find string terminator
DBM Traps
Perl5 must have been linked with same dbm/ndbm as
the default for "dbmopen()", DBM exceeding limit on
the key/value size will cause perl5 to exit immedi-
ately
Unclassified Traps
"require"/"do" trap using returned value, "split" on
empty string with LIMIT specified

perlhack - How to hack at the Perl internals
DESCRIPTION
Does concept match the general goals of Perl?, Where is
the implementation?, Backwards compatibility, Could it
be a module instead?, Is the feature generic enough?,
Does it potentially introduce new bugs?, Does it pre-
clude other desirable features?, Is the implementation
robust?, Is the implementation generic enough to be
portable?, Is the implementation tested?, Is there

enough documentation?, Is there another way to do it?,
Does it create too much work?, Patches speak louder than
words
Keeping in sync
rsync'ing the source tree, Using rsync over the LAN,
Using pushing over the NFS, rsync'ing the patches
Why rsync the source tree
It's easier to rsync the source tree, It's more
reliable
Why rsync the patches
It's easier to rsync the patches, It's a good refer-
ence, Finding a start point, Finding how to fix a
bug, Finding the source of misbehaviour
Working with the source

Implement "_ prototype character", Implement "state
variables"
Needed for a 5.9.6 release
Tasks that only need Perl knowledge
common test code for timed bail out
POD -> HTML conversion in the core still sucks
Parallel testing
Make Schwern poorer
Improve the coverage of the core tests
test B
A decent benchmark
fix tainting bugs
Dual life everything
Improving "threads::shared"
POSIX memory footprint
Tasks that need a little sysadmin-type knowledge
Relocatable perl
make HTML install work
compressed man pages
Add a code coverage target to the Makefile
installed perl
Make Config.pm cope with differences between build and
make parallel builds work
linker specification files
Tasks that need a little C knowledge
Make it clear from -v if this is the exact official release
Tidy up global variables
Ordering of "global" variables.
bincompat functions
am I hot or not?
emulate the per-thread memory pool on Unix
reduce duplication in sv_setsv_flags
Tasks that need a knowledge of XS
IPv6
shrink "GV"s, "CV"s
merge Perl_sv_2[inpu]v
UTF8 caching code
Implicit Latin 1 => Unicode translation
autovivification
Unicode in Filenames
Unicode in %ENV
use less 'memory'
Re-
implement ":unique" in a way that is actually thread-
safe
Make tainting consistent
readpipe(LIST)
Tasks that need a knowledge of the interpreter
lexical pragmas
Attach/detach debugger from running program
Constant folding

ExtUtils::MakeMaker::Config - Wrapper around Config.pm
SYNOPSIS
DESCRIPTION
ExtUtils::MakeMaker::FAQ - Frequently Asked Questions About
MakeMaker
DESCRIPTION
Module Installation
How do I keep from installing man pages?, How do I
use a module without installing it?
Philosophy and History
Why not just use <insert other build config tool
here>?, What is Module::Build and how does it relate
to MakeMaker?, pure perl. no make, no shell com-
mands, easier to customize, cleaner internals, less
cruft
Module Writing
How do I keep my $VERSION up to date without reset-
ting it manually?, What's this META.yml thing and
how did it get in my MANIFEST?!
XS How to I prevent "object version X.XX does not match
bootstrap parameter Y.YY" errors?, How do I make two
or more XS files coexist in the same directory?

Filter::Simple - Simplified source filtering
SYNOPSIS
DESCRIPTION
The Problem
A Solution
Disabling or changing <no> behaviour
All-in-one interface
Filtering only specific components of source code
"code", "code_no_comments", "executable",
"executable_no_comments", "quotelike", "string",
"regex", "all"
Filtering only the code parts of source code
perl v5.8.8 2006-06-30 177
PERLTOC(1) Perl Programmers Reference Guide PERLTOC(1)
Most source code ceases to be grammatically correct
when it is broken up into the pieces between string
literals and regexes. So the 'code' and
'code_no_comments' component filter behave slightly
differently from the other partial filters described
in the previous section.
