They do work. They do exactly as advertised in the documentation. As far as their usefulness goes, I think it is fair to say that they are not as useful as they could be, or put another way, the set of operations that are future-safe is too small to make them practical for many folks. On Mon, Se

As far as I'm aware, futures usually shouldn't improve performance outside of networking or hardware-latency type situations. The main goal of futures is just time-sharing, not improving performance. It doesn't genuinely do things in parallel, it just interleaves the execution of several things

I think the case here is a little subtle. The syntax object #'(define x y) has actually gone through expansion, but Racket's new expansion model will prune this syntax object's local scopes [1]. One could use #:local [2] in this case to see the difference: > (syntax-parse (let ([define 'something-

Fair enough. But absence of artifacts in apps you are using right now doesn't discard the same issue to show up in other apps. Google for 'display artifacts dpi scaling' or something like that. You'll see that this kind of problem is actually prevalent. DrRacket (or underlying libraries) may a

I really think it is caused by your dpi. Maybe you are suffering from other similar annoyances too like pixelated icons. Check with no scaling, if things work fine, it is nothing related to DrRacket, and artifacts like those you mention could appear on other apps too. You have still several opt
