I find that for numerics complicated iterators can
quickly become a burden. (I was glad to see that multi_array
exposes element* in the interface.)

If std::complex was simply derived from boost::array<T, 2>,
portable conversions would be immediately possible, and you
could still provide iterators where they make sense.

To put it in more general terms: encapsulation is a great
idea, but can backfire if overused (as in std::complex, IMO).
