Go's error handling is one of its single worst features. It would be much better if if had supported algebraic data types (which would also eliminate two other abominations: `iota` and `nil`, with the former being replaced by type constructors as sum types can act as enums and the latter would be replaced with an `Option` type) along with some kind of pattern matching.

If you're not familiar with algebraic data types, they're well worth learning about, and not a difficult concept. Once you use a language with them, heading back to a language without them feels like developing with one hand tied behind your back.
