👏 Looks great!

Only question is about the renaming of the type, as I am still learning TS!

Since actual type is pretty simple ([key in T]: any;) and has not changed... is it better to keep the generic name?

I might expect something named "Comparable" to check if the types are comparable like : https://stackoverflow.com/questions/53807517/how-to-test-if-two-types-are-exactly-the-same
