If you mean something like this:
(define (string-split str) (regexp-match* #px"\\S+" str))
?
If so, then I see a much weaker point for it -- unlike other small
utilities, this one doesn't even compose two function calls.
The very weak point here is if you want a default argument that
specifies the gaps to split on rather than the words:
(define (string-split str [sep #px"\\s+"])
(remove* '("") (regexp-split sep str)))
but that *does* use regexps, so I don't see the point, still...
