Hi Jordan,
The simplest change I see to your code...
(define-values (year month day)
(regexp-split #rx"/" "2012/06/06"))
...is this:
(define-values (year month day)
(apply values (regexp-split #rx"/" "2012/06/06")))
Best,
jmj

You could use match or match-let, e.g.,
(match-let ([(list year month day) (regexp-split #rx"/" "2012/06/06")])
…)

Is there a way to unwrap or explode a list? I don't see it in the docs, but it
seems like it would be a common thing.
This is what I want to do:
(define-values (year month day)
(regexp-split #rx"/" "2012/06/06"))
But regexp-split returns a list, not values, so I'd like to "unwrap" the list
an
How about this: until you find the perfect way to do this, we just add
two new optional keyword arguments to sort that deal with two levels
of key/sorts? eg:
(sort lst < #:key first #:key2 second)
would mean to sort by < for both keys, treating the first position in
the list as the main one and t

There is still a few details to attend to. What McFly Tools currently
does before calling progedit for the simpler case of "info.rkt" files
only is to identify one of 3 different formats: no module, #lang, and

Hi,
Since it's not the first time I'm having a hard time with this issue (and I
know others have too), I'm going to ask for advice or for a feature request:
Reading arbitrary Racket-related files with `read' and `read-syntax'
becomes complicated when there are #lang and especially #reader lines.
