I share Francesco's concern with making a simple variable access
trigger an arbitrarily complex operation. It is like a global
property, and as such can be inefficiently done with _G and __index.
What do we lose from having to say () ? That is explicit and clear.
I understand that the idea is to get lazy evaluation, but I think it
could be confusing to others.
