I think we're in agreement here. The "dataflow iterators" of the
serialization library is what I aways envisioned for this. It's really
a "filter construction kit". The filters used by the serialization
library (and there a number of them) are constructed by composing
simpler ones to create a higher level one. So you only need
to include enough code to get what you want. I stopped
polishing it when it was good enough build all the filters
that the serialization library required. Later boost range came
about which is a more complete implementation of this idea.

It always seemed to me that it would be interesting to use
this approach to compose code_convert facets to taste.
But code_convert facets aren't all that popular so the idea.
So it's not clear that this would be a worthwhile project.
