so did Guido:

>>> def bar():
...      yield 10
...
>>> bar()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "<stdin>", line 2, in bar
  File "<string>", line 1
SyntaxError: 'yield' outside function

(the compiler looks for a yield keyword when compiling the
function body.  if found, it creates an iterator factory, not
an ordinary function)
