Great idea!  Maybe you can get it to work within Lua's string
functions (or maybe I'm being a little optimistic).  Main use (for me)
would be regular expression search/replace operations (ex: gsub).
Modifying a Regexp library might work... (ex: posix regexp)... If my
current project's performance reqs require it.. i may implement
this... or at least some subset...

Yet another great syntactic sugar boost!  I usually cache the
intermediate table in a local...

Has there been any performance checks on the integer optimization?
Could it be faster on FPU machines?  I assume it /would/ be faster on
an intel XSCALE IX425... However I don't think I do much math inside
my proxy app.
