It would be more difficult to ensure the integrity of C libraries. See
the details of how newproxy is currently implemented. Moreover, it would
allow Lua code to define garbage-collector events; we are not sure this
is a good idea.
On the other hand, we don't see any problem in allowing __len to be
redefined for tables.
