I think, if I've understood Andy correctly, he is simply proposing that
object(x) returns true in all cases except when x has not been assigned a value,
in which case it returns false.

I agree with this as x is not truly an object until it has a value, until then
it is only a notion.

Perl has this concept with if defined(x), and even undef(x) to make x be
"unassigned".

The question as to whether to change the behaviour of the object type test comes
down to (IMHO) whether it is easy to do, whether a significant amount of code
relies on the current behaviour... oh and of course someone to actually
change/test/document the code :)
