I'm assuming chunked Transfer-Encoding, which is IIRC what the Racket web
server uses for unknown-length payloads. If the server hasn't committed to
chunked encoding (by sending the header), then it probably hasn't sent the
status code either. So truncation is definitely detectable.

AFAICT this is the intended behavior. To me it is consistent with the usual
policy: an uncaught error stops the program. If you want the program to keep
running, then you have to catch the error and make other arrangements. All my
servlet routes are surrounded by a top-level `with-handlers` bloc

Thank you, Brian and Jesse, for your thoughts on this. There may still
be an exception problem here, though.

Thank you Ryan and Ryan.
I think make-element-id-transformer is the easiest solution.
(let ([set #f]) (racket set)) is nice too because it can be used just where
needed.
I’ll try if that works around an interaction too.
An expression containing ‘set’ both as local and as imported variable rema
You can also use make-element-id-transformer, like this:
(define-syntax SET
(make-element-id-transformer
(lambda _ #'(racketvarfont "set"
Then Scribble will automatically replace SET within rendered code with the
element expression above.
Another trick is to break the for-la
My favorite way to avoid this problem is simply to choose another name, or
use `except-in` to avoid importing `set` for-label. But if you must use the
name `set` and you want it linking to racket/set most of the time (but not
this time), here is a technique I've used in the past:
