=head1 PURPOSE
Check for memory leaks.
These tests are not comprehensive; chances are that there are still
memory leaks lurking somewhere in Type::Tiny. If you have any concrete
suggestions for things to test, or fixes for identified memory leaks,
please file a bug report.
L<https://rt.cpan.org/Ticket/Create.html?Queue=Type-Tiny>.
=head1 DEPENDENCIES
L<Test::LeakTrace>.
This test is skipped on Perl < 5.10.1 because I'm not interested in
jumping through hoops for ancient versions of Perl.
=head1 MISC ATTRIBUTE DECORATION
If Perl has been compiled with Misc Attribute Decoration (MAD) enabled,
then this test may fail. If you don't know what MAD is, then don't
worry: you probably don't have it enabled.
