I have been working on a generic stato-dynamic multi-dimensional array
that can enable something like what you propose. It uses C++11
functionality (variadic templates and functions mainly). Please take a
look at: and The
developement is slow-paced because I am working on it at the rare free
time I have on weekends.
I am currently thinking of how to implement an appropriate iterator that
would be SIMD friendly. In that context I am considering something
across the lines of the interface of OpenCL and CUDA. This would work
nicely with the C+11 new for loops as well.

If you think your proposal can build on top or even contribute to
mdsdarray, I can provide a version under a Boost or MIT license.
