I was surprised that I was OK with that fact that in Rust a vector and an array with the same elements compare equal. It felt completely reasonable, and I definitely didn't feel that way about it in some other languages where that's true.

Erm, no, that doesn't work. I created a quick check in the Rust Playground: https://play.rust-lang.org/?version=stable&mode=debug&editio...

Do you have some more context? I suspect somehow things are getting coerced to slices and then compared.

The implementation isn't symmetric, it'll work if you compare `b == a`. Apparently[0] it's something to do with avoiding code bloat.
