Let's say I'm writing a program that's intended for use on LuaJIT. Is it still necessary to cache globals in local variables for decent performance, or can I expect the JIT to optimise this for me? For example: i = 0 while (i < 10000) do i = i + 1 end vs. local i = 0 while (i < 10000) do i = i + 1 end -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ "I have always wished for my computer to be as easy to use as my │ telephone; my wish has come true because I can no longer figure out │ how to use my telephone." --- Bjarne Stroustrup
