Putting everything into boost::tr1 feels like gratuitous code movement. Then
our users' migration path is from ::boost to ::boost::tr1 to ::std::tr1. Why
bother with the intermediate step?

I'd prefer to use the standard's naming convention for headers, to make it a
real implementation of TR1. There is one problem with this that I don't know
how to completely solve: some of the new libraries are extensions to old
headers, e.g., function, reference_wrapper, and bind all go into
<functional>. Can we rely on something like GNU's #include_next to allow us
to have our own <functional> that falls back to the standard library's

We should maintain the pre-TR versions at least until the TR gets its rubber
stamp, because until then the TR versions may still change whereas the pre-TR
versions are generally quite stable.
