[racket-users] Why do single-form modules behave differently?

Why does Racket handle modules with exactly one form differently? I ran into a bug where modules in my module language won't expand if the modules have exactly one form, so I'm just curious. (Wild guess: It's Racket's way of checking for a shortcut to end expansion earlier) ~slg -- You receiv

[racket-users] Do I need macros to flag unbound identifiers as failing unit tests?

Hi all, Still working the koans project and am hitting a design snag. My expected UX is that you clone the repo, run racket koans/all.rkt, and then see nothing but failing unit tests for you to fix. But since some exercises have unbound module identifiers

This is great feedback, thank you both so much! I like using a language for this approach as the project evolves, and You's feedback is a good stopgap that does work, and can be applied in-place. On Sat, Aug 11, 2018 at 1:01 PM Matthew Butterick wrote: > > On Aug 11, 2018, at 9:

Hey all, I cannot seem to create an account on PLaneT. No confirmation emails (even in Spam). Tried two browsers with extensions disabled. System does not see that my account exists and I don't see contact info for reporting an issue via the "Need Help?" link. Who do I contact for troubleshooting?

Hi! New to Racket. Looking for expert opinion on my question, but I should give some background. I worked on software for about 11 years. Started on Win32 desktop applications with C++ and then eventually moved to web, where I stayed on front-end development for about 6 years. Moved to full-st

First, thank you all for the responses. Originally I figured I would need to find some key contacts and ask them to review my Racket package* for written permission to publish under a proposed license. But if ownership itself is a question mark, I wonder if I should just pick LGPL for safety an
