Whether it's inside or outside a function should be irrelevant -- a

no influence on the type of the resulting function (and at least synchronous 
comprehensions / generator expressions
should be able to live outside of a function).

    def fun_gen():
          return list((yield i) for i in range(3))

    The return says it's returning a list, so that's what it should be returning

def f():
     yield 1
     return list()

Here return also says it should return a list, so this is not an argument.

Right, the argument is that calling the `list` constructor should return a list -- not a database proxy, not a web page, 
and not a generator.
