If you do not want to waste memory and slow down GC with proxies to objects
that exist long but are seldom used in Lua code, you should also make the 
table weak and recreate a proxy whenever one is needed and does not exist
in the cache table.

But can't this (in theory at least) conflict with the reference system?
