extension TreeSet: ExpressibleByArrayLiteral {
/// Creates a new set from the contents of an array literal.
///
/// Duplicate elements in the literal are allowed, but the resulting
/// persistent set will only contain the first occurrence of each.
///
/// Do not call this initializer directly. It is used by the compiler when
/// you use an array literal. Instead, create a new persistent set using an
/// array literal as its value by enclosing a comma-separated list of values
/// in square brackets. You can use an array literal anywhere a persistent set
/// is expected by the type context.
///
/// Like the standard `Set`, persistent sets do not preserve the order of
/// elements inside the array literal.
///
/// - Parameter elements: A variadic list of elements of the new set.
///
/// - Complexity: O(`elements.count`) if `Element` properly implements
/// hashing.
