VERSION
version 0.11
SYNOPSIS

use namespace::clean;
# Wrap a list in L<Data::Stream::Bulk::Array>
return bulk(qw(foo bar gorch baz));
# return an empty resultset
return nil();
DESCRIPTION
This module exports convenience functions for use with
Data::Stream::Bulk.
EXPORTS
Sub::Exporter is used to create the "import" routine, and all of its
aliasing/currying goodness is of course supported.
nil Creates a new Data::Stream::Bulk::Nil object.
Takes no arguments.
bulk @items
Creates a new Data::Stream::Bulk::Array wrapping @items.
cat @streams
Concatenate several streams together.
Returns "nil" if no arguments are provided.
filter { ... } $stream
Calls "filter" on $stream with the provided filter.
unique $stream
Filter the stream to remove duplicates.
Note that memory use may potentially scale to O(k) where k is the
number of distinct items, because this is implemented in terms of a
seen hash.
In the future this will be optimized to be iterative for sorted
streams.
References are keyed by their refaddr (see "id" in
Hash::Util::FieldHash).
