It's great to have support for tail recursion when implementing recursive solutions, but it is a tall order to add to more traditional languages. However tail recursion is not the only trick Racket has up its sleeve. In Racket you can&

It did. It's the standard file dispatcher that now supports keyword arguments for cache control. https://github.com/racket/web-server/commit/f82decd8bbaf8251...

FWIW a user can add this syntax himself to a language if he needs to. A hypothetical `curly-infix` language could be used like this: #lang curly-infix racket (define (fact n) (if (= n 0) 1 {n * fact(n-1)})) The reader for `curl

It was an experiment - I think the general consensus is that it was a bad idea. The double dot notation is mostly used for inequalites: (x . < . 3) instead of (< x 3) and for function contracts: (any . ->

Presumably they can see how many times a player has been reported to abandon a game ahead of time. If it is the first report, I can understand they do nothing. If it is report number 10 ...

I have used Racket on the RP400. Check https://download.racket-lang.org/ and get "Unix Source + built packages". Most likey it is your distribution that are missing the latest Racket version.

Sorry about that! I copied the Abstract from the pdf. I believe everything looked correct in the input form where I submitted the text.

And the obvious one: Scheme(r). John knows already, but the Scheme were meant to be called Schemer, but the file system only had 6 characters in the filenames. Apropos, the suffix "bit" is popular too: rabbit, orbit, gambit, picbi

If I understand correctly, the main problem was that the Pyret project wanted Pyret to run directly in the browser, so they needed a JavaScript-backend. Since Racket doesn't have a JavaScript-backend, they wrote a compiler in Pyret tha

Note that Scheme made this choice in order to make it simpler for compilers to produce efficient code.

I got some more information from Flatt. The new incremental mode means the 16ms deadline is within reach. In fact if the screen is not involved, then 1-2ms is reachable. On macOS a screen-refresh can cause a 16ms pause.

The `portaudio` is a few years old, so I have a hunch that the comment refers to the old backend "Racket BC". The new backend "Racket CS" has a new garbage collection mode "incremental", which I understand is b

Look at the "History" and "Related Links" to see where the inspiration came from (mostly Skribe, but Scribble is also mentioned).
