It would be very helpful to have a documentation for comparing all types, expected, option, outcome, and result, showing the use cases and best practices. I have some hard time to understand what one can do and the other can not and in which cases I should prefer one. One thing very obvious in this review so far is how overwraught it has made that choice seem.
I think as soon as you start writing some code using Outcome, you'll find the choice flows naturally. Using this library in your code is far, far, far easier and more intuitive than this review makes it seem. They are very simple objects, and very easy to use. Often the simpler the object, the more bikeshedding and strong opinions and noise result.
Agree, the simpler objects need to be more careful designed as they will be used a lot. This is the case for all the vocabulary types. See the time spent by the committee with optional, variant. We have not spent too much time yet for expected, but we have not finished. Maybe we could not have it at all. Nothing is ensured until it is ion the IS. Best, Vicente
