I used boost serialize with some smaller projects, which always worked

things seem to be missing.

- tuple: There is code on the Internet in various places for bridging
boost::serialize with boost::tuple. But why isn't there an official
version in either boost::serialize or boost::tuple?

*** because no one has submitted one. Feel free to submit your
version (including tests and documentation) to the vault and/or TRACK
system badger those responsable for boost.tuple to included in that

- portable_binary_archive: There are also some implementations around,
one even in the examples of boost::serialization. But why is it not in
the official library itself?

*** I made it as a demo, then I had to maintain it and it sort of became
a pain. Another problem is that the handling of various types of
Nan varied alot between systems. All in all it was a lot of work
to maintain and no one wanted to do it. I notice the current
version includes floats but doesn't deal witn Nan. I have no idea
where that came from. My current view is that such an archive
should throw an exception when trying to serialize a Nan. I've
always held the view that anyone who want's to serialize a Nan
is making a mistake - though some have strenuously argument
that there is a legitimate reason for wanting to do this.
The whole notion of portably handling binary floats is very tricky
to get right.
