Re: LUA_USERSTATE

If it involves a hash lookup, imho, yes. 

Your LUA_USERSTATE is already in there, and works, and
is useful. This was just a suggestion on a more user friendly 
interface to it.

| What about this?
| 
|   lua_pushuserdata(L, p);
|   id = lua_ref(L);
|   ...
|   lua_getref(L, id);
|   p = (mycontext*)lua_touserdata(L, -1);
| 
| 
| Too slow?
