I vote against. Don't try to change Python into Scheme or Forth or whatever. If
you find another language more expressive or elegant than Python, use that
language. I find Python expressive and elegant because it doesn't have a lot of
chaff and historical baggage.

While I'm ranting... features of programming languages aren't intuitive. Some
people may deduce the syntax easier than others, but that is experience, not
intuition. My intuition tells me that any non-alphanumeric character in a symbol
name may mean something special to the compiler; why would I think ? relates to
its English usage when _ doesn't? In the context of reading and learning Python
neither ? nor _ say anything to my intuition.
