First, the default build of Racket 7 (according to the plan Matthew posted to the racket-dev list on Feb 20) will have the new in-Racket expander, but the default will not be to use Chez Scheme's runtime. Second, the "cs" variant of Racket will map Racket futures onto Chez pthreads, and many more

Re: [racket-users] why doesn't this macro produce an "identifier already defined" error?

In the old macro expansion model marks are applied to input / output when submac is applied. Since FOO-ID is retrieved from a property it has no "input mark". We can use syntax-local-introduce to mark it ourselves. #lang racket (define foo 'module-foo) (define-syntax (mac stx) (syntax-case

[racket-users] why doesn't this macro produce an "identifier already defined" error?

I must be missing something obvious. But I've developed short-term macro blindness. The idea is that the `foo` identifier is packaged into the call to `submac` as a syntax property. When I retrieve this property from inside `mac`, it returns the expected 'module-foo value. But when I

Hola amigo, La librería `graphics` no puede imprimir texto con negrita u otra fuentes. La librería `pict` es lo que quires. La función `text`, específicamente. http://docs.racket-lang.org/pict/Basic_Pict_Constructors.html#%28def._%28%28lib._pict%2Fmain..rkt%29._text%29%29 Vincent On Mon, 21
