It was thus said that the Great Murray S. Kucherawy once stated:

I've done that successfully, but the routines in question do not refer to
local variables outside their scope, i.e.
-- might not work because bar() refers to a local variable
-- defined outside itself
local foo
function bar(x) return foo + x end
You also need to make sure any global variables referenced in the compiled
function are available in the other Lua state as well.
