Oh well :) Yes I know, but the one does not disclude the other, both versions have their uses. I could never have written my interpretation without using your code as an base.

Sometimes one just get that 'hmmm..that should be doable in x(cycles/dollars/effort/etc) less..' feeling. >Maybe I should have a look at this again in the morning when I've drunk less >beer.. :P Might make more sense.
