package Memoize::ExpireTest;
=head1 NAME
Memoize::ExpireTest - test for Memoize expiration semantics
=head1 DESCRIPTION
This is just for testing expiration semantics. It's not actually a
very good example of how to write an expiration module.
If you are looking for an example, I recommend that you look at the
simple example in the Memoize::Expire documentation, or at the code
for Memoize::Expire itself.
If you have questions, I will be happy to answer them if you send them
to mjd-perl/memoize+@plover.com.
