 //@ run-pass
-// This test ensures that type aliases can correctly accept and use type parameters.
-// Specifically, it checks that a type alias like `type Foo<T> = ...`
-// can be instantiated with a type argument without causing a compilation error.
+// This is a smoke test to ensure that type aliases with type parameters
+// are accepted by the compiler and that the parameters are correctly
+// resolved in the aliased item type.
