[boost] [Fusion] Feature Request: flat_view

    I have a request for a new type of view for the fusion library: 
flat_view.  This would operate on sequences that contain other 
sequences, for instance
        tuple<double, tuple<int, long>, pair<double, string> >
and flatten them by recursively digging into the contained sequences to 
get all of their types.  So for the example above, it's size would equal 
5 and it's returned types would be double, int, long, double, string.  I 
don't know how difficult this would be to implement, but I think it 
could be very useful.
