While Python 3 does not allow ?, it does allow characters like ʔ ( http://en.wikipedia.org/wiki/Glottalstop%28letter%29) which can be used to good effect in writing valid identifiers such as functions that return either True or False, etc., thus improving (imo) readability.

I consider “read-over-the-telephone-ability” to be an essential component of “readability”. Your identifiers containing unpronounceable characters would kill that.

Unless you're going to argue that you are writing identifiers taken from a natural language that allows unambiguous pronunciation of ‘ʔ’ with the same concision as other characters, of course.

I certainly don't want to be spelling out “U+0294 LATIN LETTER GLOTTAL STOP” for a single character when I speak an identifier.
