Hi Stephen,
I ran this small benchmark against a remote web server, and was
definitely getting better response using the http-easy module.
https://gist.github.com/samdphillips/32763ebd0d938678c2972b1dd8ee5778
$ racket -e '(require (submod "http-perf.rkt" curl))'
cpu time: 768 real time: 35299 gc
Stephen De Gabrielle and I are wondering if any Mac or Linux users
have similar short programs to make their computer talk.

Ideally you could just cherry-pick Matthew's change as a patch and
apply that during the build of the deb until the next official Racket
release is made.

Would it be possible to build a non-gui package that wouldn't need all of the

In unstable/port there is read-all. Which you could use like

Is there a useful rule of thumb for deciding if a module should be in
the racket
language or the racket/base language?

Hi All,
I understand using call-with-exception-handler/with-handlers/etc. to
catch exceptions in a block of code, but I'm at a loss to what the best
