Or only slightly, in an acceptable way (whatever that means in a given 
context). For difflib, for example, I could clean up a couple of things 
that I'd also frown upon in Python code, like taking off a bound method for 
__contains__, instead of using a straight and obvious 'in' test.

It certainly has bugs. For example, I get C compiler warnings when 
compiling the optimised difflib. And it has disabled one of my favourite 
features, inlined generator expressions. We'll try to fix it up during the 
workshop next week.
