Hmmm...I guess 2 concerns I have are 1) What is lacking in present APIs
that a Boost-style interface would provide? and 2) The design itself of
such a system could easily be a summer's work, much less any start on the
implementation, so I think it might be hard to sufficiently limit the scope
of this project to within a summer while still defining a coherent result.
