Thanks Vinícius for the review. I had actually been thinking, given your
nitpicks on the documentation, that you didn't get the premise behind
the library design at all. Looks like I got that totally wrong. Sorry
for not believing in you.

For the purposes of proper disclosure, I should say that both Vinícius
and I worked for the same startup under contract for much of that same
year in Rust, and I think it safe to say that we both took away a
similar opinion on not just Rust, but many other things. Outcome's
design is indeed strongly influenced by my time there.

With regard to the review's feedback, I should emphasise that the
monadic operations currently proposed to WG21 work with anything
matching the ValueOrError Concept, which includes both Expected and
Outcome. So when/if those land, one would be good to go with Outcome.
That is likely 2023 though, at the earliest.

Niall
