This is (should be) the exact equivalent of the Cilia code in Carbon:

• Types
  • Int, i32, i64, f32
• Variables
  • var x: i64 = 42;
  • var x: auto = 42;
  • let x: auto = 42;
  • var words: Array(String);
  • var names: Set(String);
  • var contactInfoForID: HashMap(String, ContactInfo);
• Functions
  • fn multiply(a: i64, b: i64) -> i64 { return a * b; }
  • fn print(a: ContactInfo) { ...; }
  • fn concat(a: StringView, b: StringView) -> String { return ...; }
• Loops
  • var i: i64 = 1; while (i <= 10) { ...; ++i; }
  • var i: i64 = 0; while (i < words.ssize()) { ...; ++i; }
  • for (i: i64 in (5, 7, 11, 13)) { ...; }
  • for (word: auto in words) { ...; }
