Current status:

  • Allow for parenthesisation of patterns.
  • Change @-patterns to allow a pattern on either side.
  • Add alternation (|) to patterns properly.
  • Add pattern guards (pattern if condition) to patterns properly.
  • Treat repeated variables as implicit guards for equality.
  • Change the syntax of match-expressions/-statements to take a normal pattern.
    • Or-patterns part done
    • Pattern guards done
  • ! patterns (Extend Patterns #2150)
