Support for Either type about expression HOT 2 CLOSED

Hi, I the only difference between Either and Result would be just the naming i.e Ok = Left, Error = Right, or am I missing something? What would Either do compared to Result? There is btw a choice type in https://github.com/cognitedata/Expression/blob/main/expression/core/choice.py but it hasn't that many helper functions as Result. This is the same for F#

I think this was my misunderstanding of the typing of Result -- the use of the word Error in the typing it made me think that it had to be an Exception. I've been switching between JS and Python, and forgot Python doesn't actually have a type Error even though there are a lot of Exception classes named as such.

I think more documentation would be useful on how to use Result. This is such a great library, and far less known than it should be. I think what would help for the documentation is having guides showing how to move from another language with similar concepts. A lot of the docs are F# specific or are explaining functional concepts from the ground-up. I'd be interested in writing some "migration guides" for using Expression if you're coming from Scala, Haskell, Rust, etc., since I think most people who are going to use this library will be coming from some other functional language but need to use Python now.

Closing.
