A metatable for nil?

[Gavin Wraith <gavin@...>]

There are no doubt good reasons, but why no metatable for
nil? If you forget to require a library you will have
lots of nil values being applied as functions or being indexed
as tables. It would be nice to handle the resulting
errors in a controlled way by assigning to
(getmetatable ( )).__call and (getmetatable ( )).__index.

I woke up in the middle of the night to send this query,
so apologies if the brain is not firing on all cylinders.
