Although the def version above has problems with keyword arguments. 
Still, I'd be +0 on

def nop(*args, **kwds): pass

in the operator module, in the spirit of TOOWTDI.

And I meant to add a resounding 'Aye!' to Tim's comment about the 
debugging value of None not being callable - that's an obvious indicator 
of 'I screwed up', whereas silently returning None as proposed in the 
PEP may trigger the error report an arbitrary distance from the original 
mistake.

Cheers,
Nick.
