No, this behaviour is right (now):

all luaL_check(..) triggers an error (also in lua 5.0), i.e. 
luaL_checkstring, luaL_checknumber etc. so its good to know that
luaL_checkudata does the same for now. This means, i can change
the code

        aUser **UP = luaL_checkudata(L, idx, "User");
        if (!UP)
                luaL_typerror(L, idx, "User");
        return(UP);

to a simple

	aUser **UP = luaL_checkudata(L, idx, "User");

or am i wrong?
