I guess it in some cases would be technically possible to emulate 
fixed stride with a recast to a slice of a struct with padding 
before and after the element you want.

But not very clean.

Microsoft's experimental gsl::span implementation did support 
strides, but I don't think that is possible with the std::span 
that ended up in the standard.  (C++ span is similar to D slices)
