Ok... I haven't looked into this issue. What are the various alternatives?

By operator(), do you mean indexing into an array using the notation
A(i,j,k)? If so, it's a bit unsavory because there will be some
hard coded limit to the number of dimensions you can support, and
it would be nice to avoid the kind of repetitive code you see
in Blitz++. Also, operator[] is what builtin arrays use.
