I do think it would be worth covering the symbol+keyword option discussed in PEP 531 (i.e. "?else" instead of "??", but keeping "?.", and "?[")
FWIW, I'm not keen on it.
As a technical question, would it be treated in the syntax as a keyword, which happened to be made up of a punctuation character followed by letters, or as a ? symbol followed by a keyword? The difference would be in how "? else" was treated. If the space is not allowed, we have a unique situation in Python's grammar (where whitespace between a symbol and a keyword is explicitly disallowed rather than being optional). If it is allowed, I suspect a lot of people would prefer to write "? else" and aesthetically the two seem very different to me.
