I mucked around with this, and here is my version:
class _super(property):
def __init__(self):
property.__init__(self, self.get_super, None, None)
def get_super(self, klass):
def dong(obj):
class wrapper:
def __getattr__(self, fn):
save = obj.__class__
obj.__class__ = klass.__mro__[1]
f = getattr(obj, fn)
obj.__class__ = save
return f
return wrapper()
return dong
class _superable(type):
__super__ = _super()
class W(object):
__metaclass__ = _superable
def f(self):
print "W"
class X(W):
def f(self):
print "X"
X.__super__(self).f()
class Y(W):
def f(self):
print "Y"
Y.__super__(self).f()
class Z(X, Y):
def f(self):
print "Z"
Z.__super__(self).f()
I would rather the end result look more like this:
class Z(X, Y):
def f(self):
print "Z"
Z.__super__.f(self)
But I haven't figured out how to do that yet, and the self.__super__.f()
pattern that Steven Bethard posted trumps it anyway!
