Well, the example was a bit contrived, but when deep inside a call
hierarchy, I do not find above traceback confusing. It simply
outputs the name of the chunk (or [C] in native code) and the
function in the chunk.

BTW: loadstring can be passed a chunk name. Is it be possible to do
the same with \directlua? (to replace "[string "luas[0]"]" above)
