The ? of regexes is inside strings, so I think it causes no

I was primarily addressing the fact that there aren't many
_meanings_ attached to the same character. This was brought up
before when someone talked about using an asterisk, but it was
pointed out that it would be a bad choice because it's already
commonly seen in multiplication, pointers, and exponentiation
