The bigger problem with redundant coordinates would be other machinery (e.g., for broadcasting arrays) which assumes that coordinates are unique.

For this function, the second use of the coordinate just wouldn't appear in the representation. My guess is that most functions should degrade relatively gracefully (like this one), because I usually use array.dimensions.index(dim) to determine axis numbers, which returns the first index in which dim appears.

If we want to support arrays with duplicate dimensions, we should definitely add some test cases.
