Comparing enums without their associated values

[alobaili (Abdulaziz Alobaili)]

Another interesting idea is to utilize macros for this. It's already mentioned here:

Comparing enum cases while ignoring associated values

This might be an interesting use case for a macro, which could generate a nested Cases enum with one case for each case in the outer enum but without the payloads, along with a computed property that maps the payload cases in the outer enums to the corresponding no-payload cases in the inner enum.

I don't have the knowledge to implement a macro that would achieve this, but I'm very interested in using one.
