=head1 NAME
Test::Stream::Compare::Pattern - Use a pattern to validate values in a deep
comparison.
=head1 DEPRECATED
B<This distribution is deprecated> in favor of L<Test2>, L<Test2::Suite>, and
L<Test2::Workflow>.
See L<Test::Stream::Manual::ToTest2> for a conversion guide.
=head1 DESCRIPTION
This allows you to use a regex to validate a value in a deep comparison.
Sometimes a value just needs to look right, it may not need to be exact. An
example is a memory address, it might change from run to run.
