New submission from xBrawny <and...@newthot.com>:
I wonder if this is the desired behavior. According to docs, __instancecheck__
should be called, but it never gets to it. If "return True" is replaced with
"raise Exception" the result is the same.
=========================================
class M(type):
def __instancecheck__(cls,obj):
return True
class P(M):
__metaclass__=M
isinstance(object,P)
========================================
isinstance(object,P)
RuntimeError: maximum recursion depth exceeded while calling a Python object
