Lua return

["Leandro Candido" <enclle@...>]

Hello,

    I created the script test.lua with:
------
    function test() return end
------
    Then, I executed "luac -l test.lua", the output was:
-------
main <t.lua:0> (3 instructions, 12 bytes at 00870EF0)
0 params, 2 stacks, 0 upvalues, 0 locals, 1 constant, 1 function
 1 [3] CLOSURE   0 0 ; 008701D0
 2 [1] SETGLOBAL 0 0 ; test
 3 [3] RETURN    0 1 0

function <t.lua:1> (2 instructions, 8 bytes at 008701D0)
0 params, 2 stacks, 0 upvalues, 0 locals, 0 constants, 0 functions
 1 [2] RETURN    0 1 0
 2 [3] RETURN    0 1 0
--------

Why the two returns above? This is normal, a problem of luac, or a problem
of lua?

                                                The God's Peace,


Leandro.
