Hello, I have had this PR open for a while and I really want to close it but I want some input. The current implementation might not be optimal but it does preserve the laziness of the sequence and the one I provided actually breaks that. I thought about this quite a bit and I feel like the best choice is to replace the flatMap with a filter, if that provides any benefits at all. I'd love to hear your thoughts

Hey @Giorgos Makris,

Sorry for the inactivity. I am replying on the PR directly. This signature cannot exist whilst preserving laziness by definition.

If you lazily compute Either, then there is no way to return Pair<Sequence<Either<_, _>, Sequence<Either<_,_>>>_ without computing all the results first.

Let's discuss further in the PR. Thanks for bringing this up here again 👍

The inactivity was my fault, no need to be sorry!
