Why are people disagreeing with this? This is absolutely a problem that most other languages don't have. If you want to claim that Rust's error system is "better" than anything else (as the author did), you should have a good argument about why this exact problem the parent commenter described, which to me is a major problem, does not (maybe) cancel out all the other purported benefits of Rust's error system!

This isn't a problem in other languages because most other languages don't have strong, statically typed errors that need to compose across libraries. And those that do have the same problem.

The general argument against adding something to `std` is that once the API is stabilized, it's stabilized forever (or at least for an edition, but practically I don't think many APIs have been changed or broken across editions in std).

The aversion to dependencies is just something you have to get over in Rust imo. std is purposefully kept small and that's a good thing (although it's still bigger and better than C++, which is the chief language to compare against).
