Consider that > (number? 'foo) returns #f, but (even? 'foo) is an error. If we keep the ASCII predicates so that they accept non-ASCII characters and return #f for them, what's your opinion on having an `ascii-non-control?` procedure? I know it's a bit un-Scheme-like to have the negations but can't think of anything better. This ought to be the last open question pertaining to SRFI 175; as we settle this, I'll publish a draft and announce last call.
