But that does not tell me from which line to which line to take.
It does not even work if the function was defined inline somewhere like that:

{
	foo = function()
		....
	end,
	pop = "pup",
}

There is no way to extract the currect code.
(Also this relies on debug.* instead of standard libs)

Or did I misunderstand you ?
