hi, just now I'm debugging a regular expression and trying to understand why
this:
> (regexp-match-positions #rx"[-+][0-9]+" "-0500")
'((0 . 5))
works as I expect, whereas this:
> (regexp-match-positions #rx"[-+][0-9]{4}" "-0500")
#f
doesn't. (My naive opinion is the second expression should return the same
answer as the first.)
Wondering whether I could discover for myself whether this is a known issue, I
found directly:
https://github.com/racket/racket/search?q=regexp&type=Issues
or perhaps something like this:
https://github.com/racket/racket/search?q=regexp+type%3Aissue&unscoped_q=regexp+type%3Aissue
is better, but either way I'm quickly pretty lost in terms of deciding whether
this relates to a known issue.
I'd appreciate advice on either question.
