Yes, you can see the style guide here. https://docs.racket-lang.org/style/Choosing_the_Right_Constr... The reasoning is that `define` doesn't increate horisontal indentation.

Try `racket-mode` for Emacs. It has many of the features that DrRacket has. https://github.com/greghendershott/racket-mode/blob/master/R...

> Racket's parameters are just dynamically scoped variables. More or less. Racket's parameters also work with multiple threads and cooperates with continuations. In Scheme it is common to see `fluid-let` to handle classic dynam

Well, Racket CS is "just" standard Racket running on Chez Scheme instead of the old Racket VM. Therefore no changes has been made to Racket (the language) - and thus there is no R7RS compatibility (which wasn't and still isn&

No. Racket CS depends on many features of Chez Scheme not in R7RS.

That's a different concern. Racket supports both immutable and mutable cons cells. Convenient or not - you decide. Oh, been watching too much YouTube. In both Racket and Scheme it is usually a good idea to program in a functional style

Racket does support mutable pairs. http://docs.racket-lang.org/reference/mpairs.html?q=mcons#%2...

Note that it is possible to implement SRFI-42 using `syntax-rules` - the only available macro system in R5RS.

It's not in widespread use though.

I noticed that quote as well. Odd thing to call RnRS Scheme loosely specified. The RnRS spec is extremely well-written - and it even includes a semantics. Now "Scheme" used to mean "a Scheme like language" is of course l

It's not even backwards. The voice doesn't match the languages chosen. On a machine with Danish locale it will read the french text with a danish voice. (I chose "learn french/know english")

This game reminds me of Super Cycle for the commodore 64, which also had an 6502. https://www.youtube.com/watch?v=FiebnDbq0w0 Are there any collections of source code for commercial games for the C64 ?

As you point out: Racket is different from the teaching languages.

Note that Alex Gian is porting SICM to Racket. Check the Racket mailing list for SICM posts.

Consider posting this on the Racket mailing list. If no one asks for it, we don't know what to implement next.

Greg Hendershott's `racket-mode` for Emacs is the best to work with Racket in Emacs. The reference manual is here: https://github.com/greghendershott/racket-mode/blob/master/R... It supports both `p

There is also immutable hash-tables available: http://docs.racket-lang.org/reference/hashtables.html (Just to be clear: there is of course also mutable hash tables available).

Explicit or implicit doesn't matter for compiling to JavaScript. Explicit tail calls are much better that no tail call support at all.
