Function attributes of course already exist.  They seem like they'd be
really cool to use <wink>.

But I agree.  I think we did well not introducing new syntax for Python
2.3 so we owe it to ourselves to break that bad habit. :)  

I'd also like to see syntactic support for method annotations, hooking
into descriptors.  I've been using a lot of properties in some recent
code and while they are very very cool (and IMO improve Python in some
important ways), they are still too tedious to use.  I think the method
annotation idea would be an elegant addition.
