Multidimensional algorithms?

Hi, not sure where this should go? We will soon have submdspan in C++26, which is enough to make mdspan useful in practice.

Now the next step required is multidimensional algorithms. People are apparently against having iterators, but you can just implement them yourself.

The only standard md-algorithm is the Einstein summation notation. You can easily modify this notation to be a transformation reduction rather than a pure summation. Anyone working with mdstructures probably has that algorithm already.

But my question is: are there any plans or thoughts on md-algorithms going forward?

I mean, it's nice without it, but I am an early adaoptor and I used the reference implementation to replace an existing library. That was only possible by using submdspan and adding a few custom iterators.
