[racket-users] R7RS

Does anyone know of a summary of R7RS-Small changes relative to R5RS (not relative to R6RS)? (I'm aware of "http://andykeep.com/SchemeWorkshop2015/papers/sfpw1-2015-clinger.pdf;, which addresses a different question.) -- You received this message because you are subscribed to the Google

I love n-gate, and part of the amusement is the mix of a bit of truth and being over-the-top harsh. HN has some merit, and I might also be seeing some positive shift in HN zeitgeist within the last couple months (or maybe I'm just getting desensitized to the worst, and perceptually biased to

[racket-users] racket email lists need sysadmin skills volunteer

If any Racketeer has a bit of sysadmin-type skills, and can commit to volunteering... it looks like there's a new problem with Google Groups, and a somewhat urgent need for sysadmin work on the email list hosting and archive, and then for maintaining whatever changes are made. This is

Re: [racket-users] Re: Some concern about ChezScheme...

I appreciate the engineering diligence behind Alex's and Paulo's concerns. Given the exemplary track record on Racket, I'm comfortable putting faith in Matthew's assessments (like a trusted engineering colleague, beyond the quantifiable like interim benchmarks), and there's at least some

Re: [racket-users] Some concern about ChezScheme...

I had a related (but different and small) concern about the new dependency a while ago (this was off-list), but it sounded like that risk was covered, and also that Matthew has really gotten into the Chez code. BTW, sometime around when the move to Chez settles, it would be good if many
