=head1 NAME

DBIx::Class::ResultSourceHandle

=head1 DESCRIPTION

This module removes fixed link between Rows/ResultSets and the actual source
objects, which gets round the following problems

=over 4

=item *

Needing to keep C<$schema> in scope, since any objects/result_sets
will have a C<$schema> object through their source handle

=item *

Large output when using Data::Dump(er) since this class can be set to
stringify to almost nothing

=item *

Closer to being aboe to do a Serialize::Storable that doesn't require class-based connections

=back
