it should still fix some issue In this way you can retrieve the function name and the module name where the function is.
code :
import traceback

def func():
    try:
        # My code
    except Exception as e:
        stack = traceback.extract_stack()
        (filename, line, procname, text) = stack[-1]
        print procname # function name
        print filename # module name

To fix this issue Check out the new, but well recommended Class::Sniff.
From the docs:
code :
use Class::Sniff;
my $sniff = Class::Sniff->new({class => 'Some::class'});

my $num_methods = $sniff->methods;
my $num_classes = $sniff->classes;
my @methods     = $sniff->methods;
my @classes     = $sniff->classes;

{
  my $graph    = $sniff->graph;   # Graph::Easy
  my $graphviz = $graph->as_graphviz();

  open my $DOT, '|dot -Tpng -o graph.png' or die("Cannot open pipe to dot: $!");
  print $DOT $graphviz;
}

print $sniff->to_string;
my @unreachable = $sniff->unreachable;
foreach my $method (@unreachable) {
    print "$method\n";
}

With these it helps Generally you can assign the chunk name when loading. The auxiliary function use lua_load and most will set the chunk name based on the type of content being loaded:
lua_load accepts a chunk name luaL_loadfile will use the filename luaL_dofile uses luaL_loadfile luaL_loadstring will use the string contents luaL_dostring uses luaL_loadstring luaL_loadbuffer accepts a chunk name
code :
LUALIB_API int luaL_loadstring (lua_State *L, const char *s) {
  return luaL_loadbuffer(L, s, strlen(s), s);
}
luaL_loadbuffer(L, s, strlen(s), "=my_chunk");
my_chunk:1: in main chunk
[string "my_chunk"]:1: in main chunk

it helps some times There's no direct way to access symbols from a traceback since only "code objects" are accessible and, as the Python docs on code objects say:
