But f isn't *creating* an instance here, it's just passing
on the one created by calling UserList.UserList(). If you
were to look at the definition of the latter, you would
find that it was defined using a "class" statement, making
it rather clear what sort of thing it is.

Similarly, there's nothing wrong with

  def f():
    return g()

  generator g():
    ...

Even though f happens to return a generator-iterator
when you call it, that doesn't mean I think it needs 
a special syntax.

No, it couldn't -- at least, not to anyone who really
understands what I'm saying.
