I don't see how that applies to any of the many examples I offered.
What kind of interface do you have in mind, that would avoid function
call overhead in exposing random number generation to Lua?

If what you mean is "don't do that kind of performance-sensitive stuff
in Lua, group it up in C and expose that whole thing to Lua", that's
fine--and my own approach, most of the time.  But, it's in contradiction
with the use of "performance" as a rationale for adding operators in
previous discussions.  You don't get to say performance is important
for the stuff you want--integer division--but not important for the
stuff other people want.  :)  But maybe I'm not understanding what
you mean.
