There were long discussions about various possible ways to implement
something like this, and they all had their downsides. (The PEP still
isn't fixed to describe the status quo.)
I remember some brainstorms about treating more like self. I'm not
sure
if these were thought through all the way, but I remember seeing
something like:
class MyClass(Super1, Super2):
# This method requires super:
@requires_super
def __init__(self, super, **kwds):
super(**kwds)
# This method doesn't require super:
def some_method(self):
pass
I'm sure there are drawbacks, but it fits in my head. Using super in
Python 2.0 is verbose but simple. However, I'm a little scared of
super
in Python 3.0. I guess I'm probably just a wimp.
It certainly makes me uncomfortable too. I think of all the
alternatives in PEP 3135, I'd probably prefer self.__super__.foo(),
except that I'd call it self.super.foo().
Although I don't mind reserving a non-underscore-adorned name for
Python 3.0, I could see adopting self.__super__ and using
super(self).foo() as a shortcut. To me, that addresses the main
rationale of the PEP without the magic (i.e. no need to repeat the
class).
