I'm not bothered to `switch` errors, however I really wish I could also match against both static errors (ErrSomethings) and error _types_ in a single `switch`, because now whenever I want to properly handle most errors, I need at least two `switch` statements. There's also the issue of type-matching deeply-wrapped types which is non-trivial (requiring a for loop.) If only they could solve this syntactically...
