It looks like you're misusing Devel::LeakGuard::Object::State; it says you need
to call ->done() "at the end of the area to be leak-checked".
I don't know what it does if you never call ->done().
If I put a bare block around your objects, it does what I expect:
{
my $foo = Foo->new;
$foo->me($foo);
my $bar = Bar->new;
$bar->me($bar);
my $baz = Baz->new;
}
$leakstate->done;
(Baz no longer shows up.)
Anyway, the answer is "you are misunderstanding the output"; there are a ton of
references to metaobjects because the metaclass objects are still around and
referring to them, just as they should be.
Moose and CMOP may leak, but this doesn't prove anything one way or another.
hdp.
