------------------------------+---------------------------------------------
 Has there ever been any thought to making multi_array::shape() return
 something that models the Collection concept (RandomAccessCollection in
 particular I suppose) rather than a raw pointer?  This would allow the
 return value from shape() to be passed directly to multi_array::reshape()
 or multi_array::resize(), for added convenience.  It would also allow a
 debug assertion to be added to make sure you don't try to access beyond
 the end of the array returned by shape().

 From looking at the multi_array code, it looks like it would be relatively
 easy to add a new function called maybe "size()" which would replace
 "shape()" (which could be kept but deprecated) where
 size() would return a const reference to the boost::array used internally
 to store the extent_list_.
