Canonical way to split a list of either/try about cyclops HOT 5 CLOSED

You can use splitBy, which is present on ImmutableList, ImmutableQueue, ImmutableSortedSet and ReactiveSeq to do this.

But we should add a static convenience method on Either also.

My only issue with split by is that the signature doesn't quite unpack the datatypes (which is totally reasonable/expected for a generic split by).
Seq<Either<A, B>>.splitBy -> Tuple2<Seq<Either<A, B>>, Seq<Either<A, B>>>
instead of
Seq<Either<A, B>>.eitherSplitBy->Tuple2<Seq<A>, Seq<B>>
Right now, I'm just manually accumulating, which is a pretty simple, although, really verbose workaround (and I'm not sure of its streaming vs loading into memory ramifications for larger use cases).

It would also be useful as a static method on try directly as well.

As a related question, is there a pattern for not only splitting the response try/either but also keeping the original request with it?

something where
function: request -> Try<Response, Exception>;
List requests.map(this::function)->??????->Tuple2<List<Tuple2<Request, Response>>, List<Tuple2<Request, Exception>>>
happens?

Right now I'm just manually passing along the request everywhere.

Added partitionEithers, lefts, rights as static methods to the Either class.

Merged.
