Re: [racket-users] student produces absolutely bonkers environment lookup code

Yep, I think that’s probably on the money. I guess this is really a classic example of the problem with writing code using internet search. Many thanks! > On May 7, 2021, at 4:38 PM, Ben Greenman wrote: > > On 5/7/21, Shu-Hung You wrote: >> Not that I have any idea of what's going on, but

Incidentally, a more concise way of doing this would be: (define target (build-path "tarzan")) ; convert to path only once (for/or ([item (in-directory "/tmp/test")]) ; or whatever directory you want to start in (equal? target (file-name-from-path item))) On Sat, May 8, 2021 at 3:50 AM Utkarsh
