SYNOPSIS
use Coro::Specific;
my $ref = new Coro::Specific;
$$ref = 5;
print $$ref;
DESCRIPTION
This module can be used to create variables (or better: references to
them) that are specific to the currently executing coroutine. This
module does not automatically load the Coro module (so the overhead
will be small when no coroutines are used).
A much faster method is to store extra keys into %$Coro::current - all
you have to do is to make sure that the key is unique (e.g. by
prefixing it with your module name). You can even store data there
before loading the Coro module - when Coro is loaded, the keys stored
in %$Coro::current are automatically attached to the coro thread
executing the main program.
You don't have to load "Coro::Specific" manually, it will be loaded
automatically when you "use Coro" and call the "new" constructor.
new Create a new coroutine-specific scalar and return a reference to
it. The scalar is guarenteed to be "undef". Once such a scalar has
been allocated you cannot deallocate it (yet), so allocate only
when you must.
BUGS
The actual coroutine specific values do not automatically get destroyed
when the Coro::Specific object gets destroyed.
