First of all, the first field I am interested in Computer Science can reasonably marked as Programming Language itself. Before I chose Racket, I used C and Java/ActionScript at work. now Racket is the major one (among all languages not only lisp dialects) in my life. Many people choose Clojure

On Racket, CL, limits, programmers... I've found that most stuff can be done in Racket, and, though I have used CL when required by two consulting clients' prior implementation choices, I'm not aware that CL has any key advantages over Racket. (Not bashing CL; it's a nice platform, with an

I received a direct reply from Doug. If you're strictly comparing Racket to other Lisp dialects, I would say there is never any reason to go to a different Lisp dialect. The main exception would be if there is some specific, existing capability in a different language that you require. But,

I think he's asking, when would you *not* use racket for something? What problems is it particularly suited towards, and what areas is it weak in? I'd also like to know how the list would answer this. PS sorry for forgetting to cc the list on my last msg Matthais. On Thu, Jul 23, 2015 at 9:59

Hi all - I’ve recently pushed a tweak to WeScheme’s compiler, which should do a better job matching DrRacket’s behavior when compiling lambdas-within-lambdas, and lambdas-that-produce-lambdas. I’m looking for sadistic test cases (preferably not using local) to stress-test. Anybody have any
