> if not, is there some reason lua doesn't include this? One reason is that Lua keeps track of line numbers in bytecode but not of file names: each function has only one source. In particular, what do you expect from the code below? % cat foo.lua print"1" a() $ "@hello" 89 print"2" error"boo" In one interpretation, the error message is ./lua: hello:2: attempt to call a nil value (global 'a') not ./lua: foo:2: attempt to call a nil value (global 'a') If you can live with that limitation, see the attached code (which works in Lua 5.4 and most probably earlier versions).
