I think this is the kind of mixin that belongs in the framework and, if you
don't want it, you don't mix it in.
The preferences dialog additions could be DrRacket-specific, tho.
Also, option 2 should probably have a button in the dialog that adjusts the
preference to one of the two "silent" modes

Thank you so much for this. This was definitely one area of difficulty
when I started using Racket for scripting.

(TL;DR: I'd suggest two functions: one (string-words str)
function that does Eli's way, and one (string-split str sep) that
does it Laurent's way).

Instead of trying to design a 'string-split' that is both miraculously
intuitive and profoundly flexible, why not design it like a Model-T and
then write a guide/cookbook for how to use regexps to do all of the
common cases that the extremely limited 'string-split' doesn't handle?

I always need to go check the documentation for that kind of argument

position, just like for a metho

I think Laurent pointed out in his initial message that beginners may be
intimidated by regexps. I agree. Plus someone who isn't fluent with regexp may
be more comfortable with string-split. Last but not least, a program documents
itself more clearly with string-split vs regexp.
On Apr 19,
I agree with this: we should add `string-split', the one-argument case
should be as Eli wrote, and the two-argument case should be as Laurent
wrote. (Probably the optional second argument should be string-or-#f,
where #f means to use #px"\\s+".)

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.

One string function that I often find useful in various scripting languages
is a `string-split' (explode in php).
It can be done with `regexp-split', but having something more along
