Let us see...

>>> from __future__ import generators
>>> def testfunc():
... 	return None
... 
>>> testfunc
<function testfunc at 0x010F05C0>
>>> def testfunc():
... 	yield None
... 	
>>> testfunc
<function testfunc at 0x010F2750>
>>> 

Hmm, it seems that short of analyzing the source code you cannot...

And then again, why are you interested in such a difference? Seems
like the typical YAGNI.
