Hi PyPy ers,

I was wondering why we use old style classes everywhere in the pypy code base - esp since pypy only supports new style classes (!).

I'm not sure. It wasn't my decision, you can be sure of that :-)

Would anyone have a huge objection to making ObjSpace a new style class? (Needed for the trace object space)

No. I remember thinking the same thing some time back...

Also in CPython you can

class A(object): pass class B(object): pass a = A() a.__class__ = B

but in PyPy we get "AttributeError: read-only attribute".

Is this just a TODO, or is it a feature? ;-)

Uhh... pass :-) I'm certainly unsurprised that it doesn't work right now... Cheers, mwh -- C++ is a siren song. It *looks* like a HLL in which you ought to be able to write an application, but it really isn't. -- Alain Picard, comp.lang.lisp
