A user can already have loosely related pointers tracked by using
a specialized function object and overloading visit_each. Giving
too many alternative ways to achieve the same goal may confuse
more than it helps.

I personally find a small comprehensible interface more useful in
most cases and like to find solutions based on my knowledge of the
language and not the set of available library functions.
