Hey, the formal review hasn't started yet! :-) Actually, I don't think 
BOOST_REVERSE_FOREACH is the right way to approach this. I'd rather see 
this done with range adaptors:

BOOST_FOREACH( int i, adaptor::reverse(vect) )
{
}

... where adaptor::reverse() returns an iterator_range<> (from 
Boost.Range) of reverse_iterator<> (from Boost.Iterator).

I'm working on a set of range adaptors, which I hope to add to 
boost-sandbox after Christmas. This would be a separate library from 
BOOST_FOREACH, but it would work well with it.
