@Catfish_Man Wow, to be honest, this has never even crossed my mind. But now I feel like it should have. :-)
In “everyday code”, how much of a practical efficiency win is this? I suppose in code that is more algorithmic in nature (needs to be as efficient and performant as possible), I imagine this could have a real impact, but otherwise?

@vrutberg as always it depends on the situation. If the relevant code runs once per byte of a file it might be several times faster, if it runs once per draw of a view it will be completely unnoticeable. I ran across it in some code in xcbuild that’s processing a giant pile of paths. (…then I ended up deleting the CollectionOfOne approach too and just doing integer comparisons on the utf8 bytes)
