Re: [boost] [serialization] fast array serialization (10x speedup)

Attached is a sketch of what I have in mind.  It does compile without
error on VC 7.1

With this approach you would make one fast_oarchive adaptor class
and one small and trivial *.hpp file for each archive it is adapted to. So 
that
