Yes, it is a clever solution, and works for most of the cases, great 
work.

But it doesn't work well if you only want to assign some of the 
parameters, and it leaves the variable dictionary polluted (although it 
is clear that those bindings are done).

I hope there aren't any :-)

The syntax I propose was invalid before, so it should not break any 
existing code, and the semantics are expressable in clean, normal 
python code (even preprocessor-like), so it should be compatible with 
every usage of so defined methods.
