Me too.  In my mind, this is part of qualified names so I forgot to
mention it specifically.

I think it would be nice to be ABLE to declare typed pointers,
and have the compiler complain if you tried to assign the wrong
type of address to them.  Also, I think it would be nice to be
able to directly use the result of a procedure that returns a pointer
rather than have to assign the pointer to a based variable and then
use that variable.

Maybe I was wrong to characterize this as "necessary", though.
