+/// @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.
