I am wondering if we can merge two collections to tuples if and only if the elements have something in common:

// (tuple(1, 1), tuple(2, 2))
Seq.of(1, 2, 4).innerJoin(Seq.of(1, 2, 3), (a, b) -> a == b);

the jool library has something like this.

I was searching vavr for such a function but i did not find it yet
