You know, that describes pretty much everyone who has anything to do with Rust.

"My ls utility isn't written in Rust, yikes! Let's fix that!"

"The comments under this C++-related HN submission aren't talking about Rust enough, yikes! Let's fix that!"

I'm obviously pointing to a solution: have a standard module that any Rust program can depend on coming from the language, which has a few sanely named types. Rather than every program defining its own.
