True, but it calls the GC method. My point is that I do this:
lua_pushuserdata(L, &(obj.vec), Point::getTag());
And the problem is that the GC method defined for the Point tag does
something akin to:
Point *obj = lua_touserdata(L,1);
I'm going to give tolua a try, as several have suggested.

Now I lay me down to sleep / CVS, I pray, my code to keep.
If disks crash before I wake: / format, newfs, cvs up, make.
