Can you find documentation of this claim? The Perl documentation that I've read says that Perl uses classic reference counting and does not handle circular garbage (until it has to free everything when it exits). Which is why we have Devel::WeakRef.

For instance see Reference Counts and Mortality in perlguts or Two-Phased Garbage Collection in perlobj. You can verify what that says by experimenting with DESTROY methods. They exhibit reliable behaviour that they wouldn't if true GC were in use. Else my ReleaseAction wouldn't work as advertised.
