A generic structure for a type with two possibilities: a Left a or a Right b.
An Either is right-biased, so most operations will be applied to the Right—although many operations are provided for Left as well.
This is similar to Result type in core, but is more generic.
If you’re looking for a data type to do error handling, you should use Result instead.
