It does that, but it doesn't do some other things:
if false then
a = 10
end;
lua -l test.lua
main <test.lua:0,0> (4 instructions, 16 bytes at 0x805fd10)
0+ params, 2 slots, 0 upvalues, 0 locals, 2 constants, 0 functions
1 [1] JMP 2 ; to 4
2 [2] LOADK 0 -2 ; 10
3 [2] SETGLOBAL 0 -1 ; a
4 [3] RETURN 0 1
I'm curious what other optimizations are done? I couldn't find a list...
