/// @assertion We will introduce syntax allowing you to explicitly instantiate a
/// function tear-off and a type literal for a generic class. The former for
/// consistency with constructor tear-offs, the latter to introduce in-line
/// types without needing a typedef, like we did for function types. And we do
/// both now because they share the same grammar productions.
///
/// Example:
///
///   T id<T>(T value) => value;
///   var idInt = id<int>; // Explicitly instantiated tear-off, saves on writing function types.
/// and
///   Type intList = List<int>; // In-line instantiated type literal.
///
/// @description Checks example from the Spec.
