In view of recent posts:

suggesting an interest in fixed size matrices (I guess in order
to speed execution) would it be desirable to have a variation of
multi_array where ExtentList was one of the template arguments
instead of an argument to the CTOR, as described here:

   http://www.boost.org/libs/multi_array/doc/reference.html#multi_array

?  Of course the ExtentList would just contain compile time
constants, something like mpl::vector_c<mpl::pair<index,index>,....>
where:

   typedef multi_array_types::index      index;

and the args to pair<index,index> would correspond to the args to

    extent_range::extent_range(index start, index finish)

where, of course, extent_range is the current multi_array class.
