Not completely clear to me what you want but here is a 'proof of
concept':
==========
class callsuper(object):
def __init__(self, f):
self.f = f
def __get__(self, obj, cls=None):
def newfunc(*args, **kwargs):
super(self.cls, obj).__init__()
return self.f(obj, *args, **kwargs)
return newfunc
class Type(type):
def __init__(self, name, bases, attrs):
for attrname, attr in attrs.iteritems():
if isinstance(attr, callsuper):
attr.cls = self
class A:
__metaclass__ = Type
def __init__(self):
print "init A"
class B(A):
@callsuper
def __init__(self):
print "init B"
==========
>>> b=B()
init A
init B
