bound internally by the script module for an error handler specified by function name.
Note:
This function is really intended for use internally by other parts of the lua scripting support. Although it could be useful elsewhere for advanced uses, so long as you're careful!
Warning:
You should never call luaL_unref on the value returned by this function unless you created tge reference in the first place, and even then only after having called setDefaultPCallErrorHandler passing LUA_NOREF.
