I think Dinu was just a bit overenthusiastic about Python here:-)
And I agree: ObjC is a pretty neat language. The merging of Smalltalk
and C looks
pretty clunky at first sight, but if you see the amount of power they
packed into the language with only very few extensions to C it's
Compare that to C++ with its utterly baroque set of C extensions....

I've been thinking about it. And the nice thing is that "[" cannot
occur as the start symbol for an expression, and I think a NAME after an
expression is also safe, so adding rules like
atom: '[' test methodarg* ']'
methodarg: NAME ':' test
But getting Guido to incorporate this into the language is a different
