Re: string.dump the same function is not equal?

[Rodrigo Azevedo <rodrigoams@...>]

That's not what luac says:

luac5.3 -l teste_funcs.lua
...
function <teste_funcs.lua:1,1> (3 instructions at 0x556f0d170110)
1 param, 2 slots, 0 upvalues, 1 local, 1 constant, 0 functions
    1    [1]    ADD          0 0 -1    ; - 1
    2    [1]    RETURN       0 2
    3    [1]    RETURN       0 1

function <teste_funcs.lua:2,2> (3 instructions at 0x556f0d170510)
1 param, 2 slots, 0 upvalues, 1 local, 1 constant, 0 functions
    1    [2]    ADD          0 0 -1    ; - 1
    2    [2]    RETURN       0 2
    3    [2]    RETURN       0 1
