You can give your own name to a chunk. The "string" prefix is only added
if you use the default name when loading the chunk. If you want it to
appear like a file, use "@xxx", where "xxx" is the file name. If you
want your own string, use "=xxx", and "xxx" will appear verbatim.

The core does not add a stack trace. If you don't want one, simply
do not supply one when you call lua_pcall. If you're using lua.c, then
simply set _TRACEBACK to the identity function:
	_TRACEBACK = function (x) return x end

The last argument in lua_pcall is there for this. Perhaps I'm missing
something.
