At first I thought "What? I posted that to the _beginners_ list?", but
then I remembered (or at least I remembered doing it, and google reminded
me why I did it).
Some chap had basically posted a homework question. I posted a fairly
reasonable reply, but someone else posted some code, so I asked him to
hand that one in for me too.
I wasn't necessarily after brevity or obfuscation, more fun I suppose.
I considered posting something to fwp or here, but I suppose I never got
round to it.
The "spec" for that one was at
