The salient excerpt is: "A parser is just a function that consumes less-structured input and produces more-structured output". In opposition to a validation function that merely raises an error.

    - validate(raw) -> void
    - parse(raw) -> Email | Error
Of course the type signature is what seals the deal at the end of the day. But I am going to follow this naming convention from now on.
