OK, thanks for the info. It's interesting, though, that I can code something
like this in Cython and it works:
cdef class Foo:
foos = {}
def __cinit__(self, name):
Foo.foos[name] = self
>>> a = Foo('Larry')
>>> b = Foo('Bob')
>>> a.foos
{'Bob': <foo.Foo object at 0x01C5F490>, 'Larry': <foo.Foo object at
0x01C5F488>}
>>> b.foos
{'Bob': <foo.Foo object at 0x01C5F490>, 'Larry': <foo.Foo object at
0x01C5F488>}
Perhaps I could use a hack workaround with the aforementioned count variable
by storing it inside a class level list object.
