I would not be so sure Rob Pike knows about Maybe and Either. How would he?

  Oh, I dunno, maybe the fact that he designed a programming language which practically proves he must have interest in programming languages. Combine that with the fact that Maybe/Options are neither new nor unusual in language design and fairly heavily discussed and I think it would be practically impossible for him to not have known about them a decade ago. Even failing at that, he would doubtlessly have heard of them since because people discuss them in relation to Go so often. So yeah, that's how he would know about them. They're extremely common in two areas of his interest (Go discussion/criticisms, language design).

    Failing to solve a problem is not evidence that you are familiar with any solutions.

    Given that the party line on generics in Go has been "Go doesn't have generics, but since generics are mainly used to implement generic collections, you can just use the built-in collection types for those purposes", I wouldn't be shocked if the designers of the language only had a minimal or cursory understanding of Maybe, Either, and friends. I do not mean this as a dig or an insult, but if Rob Pike is at all familiar with the benefits of Maybe and Either (or sum types in general), then it does not show either in his work or in the talks he's given.

  This is an amazing comment.

    People are amazingly able to assume ignorance is the cause of disagreement.
