Interesting. Overloading on operator= as we did with operator() is the
first thing it comes to my mind.

I tried to hide the indices (that are really only implementation
related) from the API using the constructor approach, but I think
yours is more flexible.

Default class template parameters  here ? ;-)

overloading overload::operator=() perhaps ?

I'm really curious to see your code.
