I'm attempting to do a segment group.

I have something that looks like a triple[][] but I can't seem
to get that type out.
when I add .array it converts to a Group which doesn't make
sense to me because I'm not using a unary comparison. Any
thought?
a simpler example:
import std.algorithm.comparison : equal;
import std.array;
// Grouping by particular attribute of each element:
uint[3][] data = [
[1, 1,0],
[1, 2,0],
[2, 2,0],
[2, 3,0]
];
uint[3][][] r1 = data.chunkBy!((a,b) => a[0] == b[0]);
fails in the same way.
