Well, I though just about such an operator and from the same reasons. But, as
far as I understand compilers, using such an operator will not gain much code
savings, if at all.

On the other hand it MIGHT be more readable in several places (especially
when updating a pointer who's address is given inside another structure
(like a->b->c ->= next;) but then, how meny times do you write such a code?

I think I will use this operator here and there if it will become a standard.
