Stealing some vague ideas from Applicatives in Haskell, probably wrongly but it amuses me so...

symbol_ap.rb

class Symbol
  def ap(*applied_args)
    -> *block_args {
      if applied_args.empty?
        receiver, *new_args = block_args[0]
        receiver.send(self, *new_args)
      else
        self.to_proc.call(*block_args, *applied_args)
      end
    }
  end
end

(1..3).map(&:+.ap(5))
=> [6, 7, 8]

[1,2,3].zip([2, 3, 4]).map(&:+.ap)
=> [3, 5, 7]

{ 'a' => 'b', 'b' => 'a' }.map(&:join.ap(' : '))
=> ["a : b", "b : a"]
