I completely agree. Even given that I don't know what half that stuff
means, I don't want to have to write it no matter how good the intentions.
A good syntax shouldn't be hard to relate to the equivalent algorithm,
and ought to be straightforward to translate to another language of
equivalent level.
If I had to transcribe this task to an algorithm (or just try to
understand it), I think I would go with the Ruby, Pascal or Python
versions on that site. Even the Lisp didn't look too hard.
