Note that you can forward an autoclosure to another function:
Welcome to Apple Swift version 3.1 (swiftlang-802.0.53 clang-802.0.42).
1> func foo(_ test: @autoclosure () -> Int) {
2. print(#function, test())
3. }
4.
5. func bar(_ test: @autoclosure () -> Int) {
6. foo(test)
7. }
8.
9. func baz(_ test: @autoclosure () -> Int) {
10. bar(test)
11. }
12.
13. baz(42)
foo 42
