FWIW, an unreleased Racket mode for Emacs (which did fast incremental
lexing, and some higher parsing[1]) intentionally colored the entire
expression after `#;` as a comment. I don't recall whether I decided to
have it skip over the commented expression for sibling-level sexp-based

You are correct. `--config-path` isn't really what I thought it was. That
being said, I'm no closer to understanding this default preferences window
that appears on macOS[1] GUI programs.

If only there was a way to have the best of both worlds.
E.g. change the background color for #; to something reminiscent of the
foreground color of regular comments:
(display #|Comment|#
; comment
#;(string-join "comm" "ent")
"Hello world")
Or perhaps something like t

The `math/matrix` library aims at functional arrays, that is arrays
that aren't mutated but are instead transformed into new arrays.
However, if you want mutable arrays, then you should probably use the
`mutable-array` constructor to create them, and then `array-set!` will
work.

While this does give me the value, I am unable to set it.
Calling
(define M (matrix ([1 2 3] [4 5 6])))
(set! (matrix-ref M 0 2) 5)
Leads to the error:
; .../Example.rkt:228:6: set!: not an identifier
-
And array-set! for cha
And array-set! for changing the value of an entry.

I agree that they should be shown as comments.
In many ways I like what happens (probably unintentionally) in my emacs
setup: I have rainbow-delimeters enabled, which colors the parentheses.
When I comment out the s-exp with #; the sexp looks commented out, but
the parentheses remain colored. Whi
I find the #; construct very convenient for commenting out sexps, but in Dr
Racket the visual cue of switching to comment-color is missing.
