for a simple file test.lua:
a=1
run $ luac -l -l test.lua:
main <test.lua:0,0> (2 instructions at 0xbb83b0)
0+ params, 2 slots, 1 upvalue, 0 locals, 2 constants, 0 functions
1 [1] SETTABUP 0 -1 -2 ; _ENV "a" 1
2 [1] RETURN 0 1
constants (2) for 0xbb83b0:
1 "a"
2 1
locals (0) for 0xbb83b0:
upvalues (1) for 0xbb83b0:
0 _ENV 1 0
why print negative numbers -1 -2?
a little digging around luac.c reveals that it wraps the index with the macro MYK(..).
can anyone tell me why not just print INDEXK(..) instead?
