Interesting to see that Scheme is moving forward, though not everyone is totally happy with the direction.

Arto Bendiken: R5.97RS Scheme Considered Harmful

A bit of Scheme code that I was dorking around with a long time ago and never got around to posting. This probably only works in MzScheme since it uses implementation-specific APIs to do HTTP.

Here’s an example of using it:

marc@tbird:~/projects/scheme$ mzscheme 
Welcome to MzScheme version 352, Copyright (c) 2004-2006 PLT Scheme Inc.

                (let ((result (result->struct x)))
                        (printf "~s~n" (result-url result))))
        "query=coroutines")

I’m no Scheme expert so this code is probably not particularly smart or readable, but maybe it will inspire somebody…
