This proposed new syntax is:

funcdef: 'def' NAME parameters ['[' exprlist ']' ] ':' suite classdef: 'class' NAME ['(' testlist ')'] ['[' exprlist ']'] ':' suite Why are the decorators an exprlist while the base classes are a testlist? The testlist is the list of base classes.. In both cases, the decorators are an '[' exprlist ']' That much was obvious enough :). What I meant was: Why are the decorators an exprlist and not a testlist? The base classes are a test list and the elements of a list-literal that (listmaker in Grammar) are effectively a testlist too, so it's not obvious why the decorators should not also be a testlist. Oh, sorry.. haven't had my coffee yet. In that case, I'm not sure. This is mwh's implementation, I'm sure there was a reason.

I wouldn't be :-)

Cheers, mwh
