There is a really convincing set of arguments against this idea by Robert Seacord[1]. I used to be in the signed size camp, but I've come around to preferring unsigned as much as possible because it's much easier to reason about.

Is the Rust compose backwards? Normally I would expect compose(f,g)(x) = (f∘g)(x) = f(g(x)), but in this post it's g(f(x)). In Haskell for instance, (+2) . (*10) $ 2 => 22

Breaking changes still happen, but commits to the rust repo are tagged with [breaking-change] so you can easily do a `git log --grep breaking-change` and (hopefully) get a good idea of how to fix your code. For more gradual breaking changes
