I have not yet properly had time to explore it in depth)

Yes, at the moment it looks all pretty damp, but very
interesting. For example, this really is not enough:
https://github.com/evenex/autodata/blob/master/source/spaces/matrix.d#L53-L68
The fact that no library will not arrange me. I need the tools
to work with multidimensional arrays, which will necessarily be
built into Phobos!
The matrix implementation is really just a placeholder, when I
have more time I would like to fill it out with compile-time
swappable backend implementations using the same matrix frontend
(eg forwarding arithmetic operations to gsl routines).
So yes, the matrix example is very raw (I assume by damp you
meant "siroi"). The other structures are much more fleshed out
and provide much better examples of what I'm going for (ie any of
the reimplemented Phobos adaptors: cycle, stride, etc).
The library itself is meant to generate consistent, safe
interfaces for all manner of multidimensional structures (or, at
least those that resemble cartesian products of half open
intervals).
I can drop in a naive backend later this week as a concrete
demonstration.
Its unlikely, even in complete form, that this would be suitable
for inclusion in Phobos (it adds a lot of nonstandard idioms),
but many of the design issues surrounding multidimensional
structures with not-necessarily-integral indices have been
carefully addressed; their solutions may prove useful in the
effort to build a standard library package.
