AFAIK, what Kenji implemented was just the support necessary for
implementing a multidimensional array type with overloaded opIndex /
opSlice / opDollar. I don't think there's any functional / range-based
things actually built on top of this at present.  I'm also quite
interested in this topic, and several people in the past have also
voiced similar interests. But I don't think we have anything standard
just yet.

In any case, what Kenji did was basically to implement support for:

	arr[i,j,k,...];		// opIndex
	arr[i,j,k,...] = ...;	// opIndexAssign
	arr[i1 .. i2, j1 .. j2, ...];	// opSlice
	arr[i..$, j..$, k..$];	// opSlice / opDollar

and perhaps one or two others.

And, looking at the docs on dlang.org, evidently this feature isn't
documented yet. :-(  Maybe if I get some free time later today I'll take
a shot at documenting it.
