Hi Neil

Ultimately the signature you suggest is what I want to call, however I was
hoping to achieve this via recursive instantiation, largely because looping
over one index in the implementation is easily achieved with a for_each
loop and a bind() call, whereas looping over two indices is rather
In practise there's also some other house keeping, which makes the
recursive instantiation approach quite attractive.

The exact match case you present is spot on, and in fact was my first cut
at this functionality. What I'm unclear on is why the single dimensional
is not also an exact match with appropriate inferring of T.

Thanks for your thoughts.
