I would love if they added "?" to the list of valid characters for names, so I could write something like `valid?()` instead of ``is_valid()`.

just use "_P", a fairly-widely-recognized substitute from the Lisp world.

As a python programmer I would have no idea what `valid_P` is supposed to mean. Valid Pascals?

P is shaped like a question mark, though I think it was retronymed to stand for "Predicate"

The suffix is just "p" in Common Lisp[1], so I think the "predicate" explanation is more likely to be correct than the visual analogy to the question mark.

Or even better, just `valid?` Oh, wait .... that's Ruby.
