Well, I shoulda kept my mouth shut, got me again:-).

Tried to whip out the simplest trial I could find for basic
flow-of-control stuff, ruby beat out perl, although not too
horribly:-). ruby-1.6.0, perl 5.005_03, scripts appended, simple
count to a million by incrementing calling a subroutine to do the
increment, elapsed time(1) under Red Hat 6.2 on a P300 Mobile MMX w/
128MB RAM, doing very little else, best time of 3 trials (they had
very little variation in the runs):

	1.perl 7.16
	1.ruby 6.00

I tried to whomp it up in lua but I'm not a lua programmer, and Lua
4.0alpha (I've not been able to snag the 4.0beta yet) barfs on my
naive attempt. I'm so not a schemer that I didn't even attempt to
write it in qscheme. So much to do, so little time for play:-(.
