It's entirely possible that Perl will be used on virtual machines
where this can't be done.
I'd suggest that we simply declare that every metaclass must support a
".all" method which returns an arrayish thing containing all active
objects it is managing:
grep { .isa($class) } MetaClass.all;
Whether this works by interfacing with the garbage collector, keeping
an array of weak references, or waving a wooden wand and yelling
"Accio objects" is completely up to the metaclass in question.
