Let's say you have a size of an image, store it in a 2D vector. A position in 2D or 3D? Store it in a 2D or 3D vector respectively. A velocity for something? 2D or 3D vector. An axis-aligned box? That's just two 3D (or 2D) vectors of course. A coordinate for the mouse ...
Wouldn't work e.g. forx::SparseMatrixCSC. I'm all ears for reasonable semantics here -slicedimalways returning an array, even if 0-dimensional doesn't sound bad at all - but specifying them in a generic fashion seems a bit non-obvious. And it would be really nice if we could provid...
