I’ve said it before, but I don’t think `times` is a good solution for learners.
It teaches them a form of looping they will never use in practice and does not
allow them to practice with ancillary loop skills like `break` and `continue`.
I think our best bet is to extend the `for` loop to allow a single number,
meaning either `1…n` or `0..<n` (you can argue it either way), and also to
allow the `variableName in` part to be omitted, meaning `_ in`. This gives us
the pedagogical simplicity of a “do this N times” loop, but couches it in a
form where, when the student moves on, more commonly used loop forms are a
straightforward extension of that simple case.
for 5 { print(“Hello!”) }
for i in 5 { print(“Hello \(i)!”) }
for i in 10..<20 { print(“Hello \(i)!”) }
for i in 10...20 { print(“Hello \(i)!”) }
