Yes.

No.

Realistically, I will not be able to work on this before September (due to
travel). More realistically, it might take even longer unless a miracle
happens. If you want, we could approach this incrementally: you establish the
slot in the doc tree (like the caption and the first sentence of the intro), I
fill in a little, you rework it a bit, I rework it a bit, etc. That would
probably help a lot in getting it done sooner rather than later, and cut down
significantly on the time-consuming need for writing lengthy e-mail messages.

We could start this way with the code: 1. you copy the relevant fragments from
the files where you think they should go (to boost cvs). 2. tell me where they
are and I'll fix them up so they get build with bjam, and I'll turn the
assertion based tests into doctests. 3. go through and fix the code up as you
see fit (be as intrusive as you find necessary); tell me when you are done and
I see if I can still use it in our package. etc.

To get things off the ground, I'd suggest to limit ourselves initially to
"measurable" sequences (that's what the code is doing now; checks should/could
be added). /Later/, when we hopefully have boost::python::sequence and
boost::python::iter(ator) we can adjust the "to STL container" converters to
deal with both.
