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).
