>          Issue Type: Improvement
>          Components: Java API

>            Priority: Minor

> Currently the method signatures for creating Either values `Either.left(left)` and the projection methods `either.left()` only differ in the parameters. 
> This makes it awkward to use with lambdas such as: 'eitherStream.filter(Either:isLeft).map(Either::left)'
> The above code is currently impossible.
> I suggest to change the creation methods to `Either.createLeft(left)` and `Either.createRight(right)` and also to directly expose the Left, Right classes.
