Re: [racket] Help with simple macro

Thanks to this Eli, I now see what parameters are. By chance I also just came across your's, Ryan's and Matthew's article "Keeping It Clean with Syntax Parameters" http://www.schemeworkshop.org/2011/papers/Barzilay2011.pdf that makes crystal clear all the issues about the question I asked. Cheers

[racket] Functional Data Structures for Typed Racket?

I'm pretty keen to try out some of the new data structuresfor typed Racket, but they haven't landed yet--either in 5.2.1, or in the repo last I checked. Is there any notion of when I might be able to get my hands on them? -- Simon. ___

[racket] Can't figure out how to use module after raco planet fileinject

Hi, I created a planet archive locally with raco planet create, then I installed it into my local cache with raco planet fileinject. All I've written in Dr Racket so far is: (require (planet "something.rkt" ("shawnps" "something-racket.plt" 1 1))) and it runs fine. I can see it in the module b
