+1 for throwing it out of the PEP. Assignment is a thing, nonlocal/global is a thing, don't mix them up :) (That in addition to the grammar cleanliness argument Stephan already made)

The trouble is what to make of

nonlocal x = 3, y

Is it two nonlocal declarations or one with a tuple assignment?

I'm not sure I understand. Isn't that another reason to throw it out? If you don't allow such assignments, there can't be any ambiguity, right? (Or am I missing something?)

Yes and no -- there may not be an ambiguity to the parser, but still to the human. Except if you disallow the syntax in any case, requiring people to write nonlocal x = (3, y) which is then again inconsistent with ordinary assignment statements. Georg
