Thanks. This indeed is probably the best one can do now. But doing this
spoils the "convenience feature for programmers" part. And it is MUCH
slower than accessing value through a direct pointer.
Basically my question is whether any code other than the lua_setfenv and  
lua_getfenv depend on
Udata->env being a (Table *)? If adding dozen lines to the core means I  
don't have to
create extra table, and it doesn't break anything, I think it's worth  
doing.
