Syntactically, there has to be something in the function definition. It can
be a `pass` statement, or a doc string, though:
Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41)
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> def f():
... "empty function"

>>> f()
>>> print f()
None
>>> def g():
...
File "<stdin>", line 2
