Years and years of discussions about Go's poor and verbose error handling, with multiple sensible proposals being rejected, and this is the improvement that finally makes it into a release?
What Go demonstrates above all else is how successful a poorly designed language can be if it has a great compiler, an amazing standard library, and high-quality official tooling. Many "features" of Go are borderline insane (date formatting, lack of enums, implicit interfaces, ...) and Go repeats design mistakes that were recognized as mistakes decades ago (nil pointers), but all of that is happily overlooked in practice because huge codebases compile in three seconds, you don't have to argue about which formatter configuration to use, and everything from TLS to CSV is rolled into std without ever having to import a third-party repository.
