I have no idea why that's relevant.
Why not? PEP or FAQ if there is one.
Because programmable syntax isn't something we want in Python; you yourself quoted an email from Guido explaining why. If you like the idea of allowing every module to define its own syntactic constructs -- at runtime or otherwise -- Perl 6, Haskell and others are more than happy to help you. Collin Winter
Huge bag of worms, I see now. I was tinkering for hobby Python use. I hadn't proposed a syntax change, not there yet. I was wanting to intercept parser somewhere after it's started parsing source, but before it gets to the rules. The particular change I'm tinkering with was replacing an equal sign with a natural word. 1, 2 to a, c -and- to a, c 1, 2 map to: a, c = 1, 2 Like I said, trivial, but I was hoping a small change to parser would work. (It's not always unambiguous either.) But here's the idea.
