Take a look at the implementation of debug.traceback, which shows how 
to use the debug/introspection API to produce a traceback.

The fourth argument of lua_pcall allows you to specify an error 
function which will be called when an error is thrown, before the stack 
is unwound. The stand-alone Lua interpreter uses debug.traceback as 
this error function.
