Agree. I've used Eigen a fair bit. At least as much as I have Qt. Eigen
is one polished wheel I certainly wouldn't want to re-invent.

I'm just wondering out loud if it would be a good thing to have a numeric
vector type that supports math operations (and optionally will SIMD
accelerate them). Qt supports some fixed dimensionality vectors
(QVecorXD, x={2,3,4}). But this would add flexibility for say, machine
learning applications. The only collision that I know of is length()
where the existing fixed-dimension classes provide magnitude as length().
Additionally it may be useful to support non-Euclidean spaces, though I
wouldn't see much use beyond polar (haversine) distances and bearings.
Thoughts?
Use Eigen?
There's a couple of classes in Qt3D that do 3D and 4D vectors with SSE2 and
AVX2 acceleration, but I would really like you to use Eigen instead.
