Ah! GTK :)

That's why I hadn't mentioned it before now, either. Not much point.

Personally, I think that the most "Pythonic" prefix form would be:

class C:
   decorate (d1, d2, d3):
     def f(self):
       pass

But down that road lies madness... *ducks*

Not an abomination, no. I just think it fits better inside. It's nicely 
scoped, it's contents are well delineated, it doesn't couple with the 
next statement at the same indentation level, and plays nicely with 
where we already look for the docstring (for now). Of course, it couples 
with the outer scope, but docstrings already set the precedent for that.

It just seems more "Pythonic" to me to have it inside, is all.

There's that word again... :)
