Perl 6

Features to add once Rakudo implements them

• Arithmetic Evaluator:
  • Use make to create a much more digestible parse tree.
  • my grammar. I'm not certain you're supposed to be able to do that, but I think so.
• Comments: Nested bracketing characters.
• Creating a Function:
  • Not quite the same thing (see Synopsis 2): <lang perl6>sub multiply (Int $a, Int $b) as Int { $a * $b }</lang>
  • &multiply = [*];
  • &multiply = &infix<*>;
• Monty Hall simulation:
  • :delete adverb.
  • More trials.
• Playing Cards: There really ought to be something like EnumerationType.pick(*) that gives you the values of the enumeration in order. You'd think Two .. Ace would do it, but as of Rakudo release #22, that produces numbers, not Pips.
• Trigonometric Functions: The base-switching interface specified in Numeric.pod.
• True/False Values: 0 but True.
