These are features which we might want to consider for removal or replacement with something better/cleaner.

  • n + k patterns
    • For removal: we have been saying it will happen for a while now, we should make good on it.
  • ~ patterns
    • For removal: can be simulated with 'where' or 'let' clauses
    • Against removal:
      • fine control of strictness can require careful placement of these and let/where would obscure what is happening and get very verbose with nested ~ patterns.
      • are used in several safe programing idioms that would not be workroundable.
  • the monomorphism restriction
    • classes (no really, there are people who advocate this!)
    • the Prelude (or at least, seriously trim it to the minimum possible)
    • defaulting
    • class contexts on data definitions
    • record syntax
