Then you can at least try and use lazy evaluation:

That gives a lot of free lunch.

Since Lua GC means that lifetime of _any_ object can extend arbitrarily  
long (or until next gc "collect"), there is no way to automatically  
reclaim temporaries other than writing hacks that will be incorrect in  
corner cases.
