But I don't want to read your cute custom hashmap code. Go really shot for the stars with its primary design goal of uniformity. The hashmap you're using is the same one I'm using, is the same one any random Go repo on Github I open uses. The value of this is immense—I instantly feel right at home, I know the exact semantics you're using—we're speaking the same language.

To wit, I would argue that Go didn't go far enough in restricting the user and certainly did not pick the right features to include. I don't think it's clear at all that had go shipped with sum types—enabling better error handling—and iterators, more built in generic data structures, and higher level abstractions around its concurrency, but no generics at all, that we wouldn't end up with a far better language. A more restricted one, with even less room for anything custom, but a better one.
