Today I have submitted a proposal for "memorization", "memo", "memorize" keyword for a function that allows to run only once through out the lifecycle in Swift 3. Repeatedly execute the function will only return the same result without having to rerun the function everytime. As far as, I don't see my submission is being visible for discussion.

  memo func hello(fname: String, lname: String) {
    return fname.lname
  }
