Is there any way in PASM to determine whether or not two PMC's share the
same memory address?
Not yet. We have the vtable methods but the opcodes are missing.
We have:

As outlined some time ago, when ops.num made it into the core, we need
fix assigned PMC class enums too. (Changed class enums invalidate
existing PBC files).
1) lib/Parrot/PMC.pm is the canonical source of PMC class = enum mapping.
2) the class enums should be numbered so that base classes come

There is delegates.pmc
Can someone add a pause to parrot, presumably similar to the existing

I think this is definitely something we should do if we want to confuse
people as much as possible :-)
This is likely true, seeing as I *still* have troubles keeping the various
Lisp eq/eql/equal/equalp's straight. ;)
I would therefore vote that we keep these opcodes as verbose as
possible.
We're already using 'eq' to perform equality testing, and in the interests
of maintaining a consistent design I would choose to stick with something
eq-related as opposed to changing it to 'same'.
eqaddr/eqval? eq_addr/eq_val? eq_address/eq_value?
Oops, correction there - I'd forgotten an

Or as verbose as needed [1]:
