Boa noite,
Necessito criar radio-boxs dinâmico, estou usando um for e um contador para
realizar a criação de cada um dos radio-box. desta maneira:
(define que (string-append "questao_solve" (number->string count)))
(print que)
(set! que (new radio-box%
I think that is is possible to add an unofficial CS target to
travis-racket (https://github.com/greghendershott/travis-racket) using
something similar to https://github.com/racket/racket/pull/2266 . For
now it will be slow because it will have to install a normal Racket,
ChezScheme and recompile

Hi, Yasser. The reason I asked those questions offline was that,
Some follow-up to my previous message (which, I guess, everyone was waiting
for given the seemingly large interest :)
I tried using quickscript to get access to the interaction window and add
the snip from there and it works.
I feel that this might confirm my hypothesis regarding not being in

Also a few days algo there were some more updates at RacketCon and
Scheme Workshop.

If by lately you mean any time in 2018 there is Matthew's report from back
in January.

If you are feeling adventurous you can also build it from source
I'll answer anyway, because the `begin0` difference is subtle.
At the level of `let`, the Racket optimzier goes out of its way to not
convert your second program to the first. Continuation marks make a
change from non-tail call to tail call observable, and in this case,
the compiler won't be able
Actually nvm. Whoever wrote such macro could have just used `begin0`
instead.

Hey, could you provide a resource with more information on Chez
possibly
replacing the Racket VM? I haven't been keeping up to date on
this.

That's a good idea. It won't happen this week, but maybe it can happen
in November or so.

Would it be feasible and useful to start building Racket-on-Chez snapshots
along with the other variants at https://pre.racket-lang.org? In light of
the promising outlook for Chez replacing the current Racket VM in the
relatively near future, I would be interested in starting to include it in

Problem with using `require` is that I'll have to use "#lang racket" with
it, which will prevent me from using
Leandro, obrigado por esta excelente contribuição.
Thank you for this excellent contribution. It's really good. I am
reading it a bit at a time and I really enjoy it, not only how you write
it but the subject as well.
Racket needs more of this.

I attach yet another example where this behaviour is much more
noticiable. This is on a 64 core dedicated machine in amazon aws.

Hi,
I am not sure this is an issue with places or what it could be but my
devops-fu is poor and I am not even sure how to debug something like
this so maybe someone with more knowledge than me on this might chime in
to hint on a possible debug method.
I was running some benchmarks and noticed
