I have been working on extending the functionality of
multidimensional arrays using mir.ndslice, and now einstein
summation is available.
It may not be practical, but it can be described nicely, like
below, so I will introduce this.
```D
auto A = iota(9.).array.gged!double(3,3);
auto x = iota(3.).gged!double(3);
auto Ax = Einsum | A.ij*x.j; // [5, 14, 23]
```
Very nice. Do you plan to make it `@nogc nothrow` like
mir-algorithm?
