What's wrong with
(os.path.join(d, x) for x in os.listdir(d))
It's short, and easier to understand then some obscure option ;)

Just a guess, but setting "__X__" special methods won't work in most cases
because these are usually optimized when the class is created.
It might work if a.__call__ did exist before (because class a: contained
a __call__ definition).

Names are nothing magic in Python, and quite easily manipulated:
import os
os.write(1, "Hello World!")
class os:
pass
o = os()
import os
os.write(1, "\n")
So basically this kind of name clashes usually do not happen in Python.
Or another usage:
os = SomeObject()

I'm sure it's documented somewhere, but here we go :)
The correct usage is super(MyClass, self)
The idea is that super allows for cooperative calls. It uses MyClass to locate
what class "above" to call.
This way you can something like that:
class A(object):
def bar(self):
print "A"
I'd consider taking a look at the re module ;)

Well, It means that eval(repr(x)) == x if at all possible.
Basically:

You'll notice that 'abc' is a valid python expression for the string,
while abc is not a valid string expression.
