I think there are two reasons that code gets slower. 1. The `match-define` includes pair and struct checks, which are omitted for plain accessor uses because of the unsafe declaration. 2. That use of `match` expands to `define-values` which ends up as a `call-with-values` and a `case-lambda` at th

First, there's no longer a difference because yjqww6 just had a PR merged that improves the Racket performance. The performance difference that was there was mostly because the Chez code was run with `--optimize-level 3` which turns off safety. If that was changed to `--optimize-level 2` the timin

Hi guys, I’m trying to find out what this process may be called. Suppose you have lists of various lengths: ‘(A B C D E F) ‘(1 2) ‘(3 4 5) And you want tho produce the following: '((A 1 3) (B 2 4) (C 1 5) (D 2 3) (E 1 4) (F 2 5) (A 1 3) (B 2 4) (C 1 5) (D 2 3) ...) As you can see each element

Re: [racket-users] Racket v8.0 (!)

I think your 32-bit options at this point are these: 1) Use one of the nightly builds, e.g. https://plt.cs.northwestern.edu/snapshots/ 2) Compile it yourself, using the source bundle. 3) (Of course, you could use an older version. Looks ilke 7.3 is the last one released in a 32-bit Linux build.)
