I’m more excited about File::lock and friends. I don’t currently have a use-case, but surely it’ll help w/ something like a SQLite implementation in Rust.

Result::flatten() is probably my favorite addition

It’s rare to a have a negative reaction to a library addition. But I don’t like this one at all actually.

For me, error contexts are as important as the errors themselves. And ergonomically helping with muddying these contexts is not a good thing!
