=head1 NAME

Test2::Compare::Pattern - Use a pattern to validate values in a deep
comparison.

=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 that might change from run to run.
