Yes, it sounds like a custom container. But I can't figure out how the
slot call argument can be changed. Deferencing the provided
InputIterator calls the slot with the default argument, AFAIK.

[Nat] You're right. Now the question is whether the machinery underlying
the Combiner iterator-dereferencing mechanism is available for public
consumption, or is messy implementation detail. For that I'll have to
defer to someone more familiar with Boost.Signals internals.
