What is the cleanest way to turn a Vector of vectors of unboxed doubles into a repa Array U DIM2 Double?

The most obvious way is to concatenate all the unboxed vectors into one and pass it to fromUnboxed, but that feels a bit clumsy. Is there a better alternative?

The thing is, repa `Array U` is basically just a newtype wrapper around an `UV.Vector` anyway, so I don't reckon there's much of a better solution. – leftaroundabout Mar 13 '17 at 11:47
Ah right, thanks @leftaroundabout. Add an answer if you like so I can accept it – Rob Agar Mar 13 '17 at 15:50
