devel/p5-Test2-Tools-MemoryCycle 0.01 FreeBSD

Perl's garbage collection has one big problem: Circular references can't get cleaned up. The above example is the sort of thing that sometimes trips me up, where a code reference inside a data structure refers to another part of the data structure. There already exists a good testing module to find these sort of problems: Test::Memory::Cycle, so why write this one? Well that module uses Test::Builder, and this one instead uses Test2::API. If you want to write Test2::Suite tests without pulling in Test::Builder then this is the cycle testing module for you.

Test2::Tools::MemoryCycle also uses the standard Exporter interface, instead of letting you specify a test plan. That behavior was once in vogue I guess, but I do not care for it.
