Data::Stream::Bulk::Util - Utility functions for Data::Stream::Bulk

# return an empty resultset
This module exports convenience functions for use with Data::Stream::Bulk.
Sub::Exporter is used to create the import routine, and all of its aliasing/currying goodness is of course supported.
Creates a new Data::Stream::Bulk::Nil object.
Takes no arguments.
Creates a new Data::Stream::Bulk::Array wrapping @items.
Concatenate several streams together.
Returns nil if no arguments are provided.
Calls filter on $stream with the provided filter.
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).
