Indeed; I can see it in the luac output.

So luac does have the information about the main chunk and the compiled function. Is there any way to get this information using debug.* functions without calling luac or executing the code?
It seems like luac has information about all the levels of functions in the code; for example, the following fragment:
local function b()
shows one main chunk and two functions:
main <test.lua:0,0> (3 instructions, 12 bytes at 007B1170)
function <test.lua:1,7> (8 instructions, 32 bytes at 007B12A8)
function <test.lua:3,5> (4 instructions, 16 bytes at 007B1B98)
If luac output does have all this information, why is it not available through .activelines for that chunk? Is there any way to get to it?
