Yeah, you're right -- IIUC it's very much like Python decorators, though
not class decorators but function decorators, right? IANA Python expert.

Ingvar, I've read your proposal more carefully. If I'm reading it right,
I think your description is off a meta-level-- it's not so much a
general syntactic sugar mechanism as a way of defining one specific kind
of sugar: a function decorator. Basically, a decorator is syntactic
sugar for function composition. The first thing I'd change is to replace
the "sugar" keyword with "decorator." I think this would make its
purpose clearer and connect it with precedent from other languages.
I guess I don't have much of a reaction... I understand people get a lot
of mileage out of Python decorators, but if it came down to choosing
between decorators and macros, I'd take macros. Regardless, I don't
think we've been considering meta-programming facilities to be on the
near-term agenda.
