If you're talking about string manip, maybe... that's what perl was designed
for. Everything else is sorta hacked into the interpreter. Not in the most
efficient way, either, I might add.

I haven't timed Lua and Ruby against each other for common operations, but
I've seen results in various "Language Comparison Papers" around the web, and
Ruby takes the lead in most of them. I'm interested in what benchmark
programs you used?

Again, no idea how you got your numbers there... perhaps you compiled your
own Ruby, and either did a debug build or didn't strip the binary? I
installed both of these through the Mandrake Cooker RPMs (I'm running Linux
Lua certainly does win in size, though, I'll admit that. I'm going to
benchmark Ruby and Lua as soon as I get the free-time (I have to leave for
class in 10 min.).
And yes, that is Perl 5.6.0 (I've only seen those versions numbers under
Mandrake....). Ruby is version 1.6.

Ah, yes, that one is insanely fast too... Too bad scheme isn't the most
newbie friendly language, or it'd be great for games (most games scripting
need to be done by non-programmers, or perhaps the user-community mod
