Me neither.  I'd be interested in hearing if it was a design oversight
or a design decision.

Short of changing your example to be

void foo_ref(array_3d::array_view<2>::type& ma)
{
    ma[0][1] = 1.0;
}

I'm unaware of another non-templated solution.   I expect that I'm
wrong, however, and that something prettier should be possible.
