With a good FFI it seems like someone could write a great Racket DSL for

I know very little about it, but it looks like it covers stuff that racket
includes as built in functionality.
Yeah, I don't know Node.js, but most of "http://nodejs.org/api.html";
looks like ways to make JavaScript more easily do things that Racket
already does better than Node.js does.
Regarding event-driven API like I see in the documentation for Node.js
"net.Server" documentation, you could implement that in pure Racket
pretty easily, without needing FFI.
I've done some fairly high-performance I/O for TCP and interactive
subprocess pipes in pure Racket. Racket's own event conception, buffer
operations, and multithreading have been up to the task. Of course,
Racket certainly lets you implement simpler abstractions like Node.js's
atop this. You can even make Racket special-syntax like
"define-Node.js-like-server-and-with-some-static-checking". :)
