Regexps are very powerful, but they are complicated for beginners.

I think `racket/string' should provide the useful string functions,
rather than refer users to srfis. The only srfi/13 function I ever
use
(define (string-split str [sep #px\\s+])
(remove* '() (regexp-split sep str)))
Nearly, I meant something more like this:
(define (string-split str [splitter ])
(regexp-split (regexp-quote splitter) str))
No regexp from the user POV, and much easier to use with little knowledge.

Continuing with this line, it seems that a better definition is as
