I pushed to the wrong branch in racket/games :( https://github.com/racket/games/tree/19-10-SameTypo Is it possible to remove this branch to avoid confusion? Gustavo PS: There is another branch in that repo that looks like a similar (old) error and a few branches in racket/racket. Perhaps it's

Re: [racket-dev] Is there a way to contribute to the Racket on Chez conversion?

One posible idea that I think that would be indirectly useful, is to translate the instructions of Matthew to an example in Travis-CI that compiles the RacketCS and then run an small amount of tests. This requires some knowdledge of the quirks of Travis-CI, so I'm not sure if it is newby friendly

Re: [racket-dev] #:authentic

Somewhat related ... I always thought it was strange that mutable pairs can’t be chaperoned, but boxes and vectors of length 2 can. Moreover, there was (is?) a plan to replace the implementation of mcons with structs. Does #:authentic make this more consistent / efficient? Also, what would

Re: [racket-dev] Release Announcement for v6.8

What about something like: The bytecode optimizer can reduce more expressions like (equal? x y) to (eqv? x y) or (eq? x y), in case the type of x or y is known and the comparison is equivalent for that type. Gustavo -- You received this message because you are subscribed to the Google Groups

Re: [racket-dev] toward a new Racket macro expander

I'm still not sure that this is related, but in the old system two equal consecutive marks cancel. But if you compose two markers, the composed mark doesn't cancel when it's applied twice. For example: ;--- #lang racket (define A (make-syntax-introducer)) (define B (make-syntax-introducer))
