at times we require reading access to an nD array at given coordinates, as a functor which, receiving the coordinates, produces the values from the array. In the scalar case, this is trivial: if the coordinate is integral, we have a simple indexed access, and if it is real, we can use std::round to produce a nearby discrete coordinate. But for the vectorized case we need a bit more effort: We need to translate the access with a vector of coordinates into a gather operation.
