Indeed, however if I read it right filter_iterator requires a predicate,
just as boost.adaptors.filtered does,
and the construction of the predicate from a method requires the explicit
use of bind, or mem_fn, whereas
I'd hoped to see a facility offering an overload that accepts a
pointer-to-member directly.

Thx, R.
