Parrot 1.1, base types and inheritance

[bsdz]

Hi all,

I notice that Parrot's inheritance and base types seems to be pretty
much inconsistent and unusable. Here is a list of tickets that
instinctively feel similar.

https://trac.parrot.org/parrot/ticket/218 - can't sort a PIR subclass
of an RPA.
https://trac.parrot.org/parrot/ticket/562 - subclassing basic number
types fails to inherit basic ops like add, sub, mul and div
http://rt.perl.org/rt3/Public/Bug/Display.html?id=59630 - Complex
subtraction fails for subclasses of Complex
https://trac.parrot.org/parrot/ticket/556 - setref on derived pmc
aggregate class loses data on return
https://trac.parrot.org/parrot/ticket/203 - assign_pmc broken for pir
subclasses

Can we add some priority to getting inheritance fixed to the next
milestone, perhaps 1.2? Can anyone bring this up in the upcoming
#parrotsketch?

Thanks
Blair
