      error text.

    • 🛠 Fix ghc 7.10 warnings
    • ⬆️ Bump dependency bounds
    • ➕ Add maybeReader function for convenient ReadM creation

    • 🛠 Fix hsubparser metavar override
    • ✂ Remove ComplError, which was dead code.
    • 📜 Reimplement Missing error generation, which overly complicated evalParser.
