The actual type argument in the type annotation `Foo<String>` should be a
subtype of `num`, not just assignable, so we ought to adjust this comment.

 Foo
-    <String> //# 02: static type warning, dynamic type error
+    <String> //# 02: compile-time error
     fs;
 
 class Box<T> {
   // Box.T is not assignable to num.

[eernst, 2017/09/04 17:05:02]

Same issue: adjust to `Box.T is not guaranteed to be a subtype of num`.

-  Foo<T> t; //# 03: static type warning
+  Foo<T> t; //# 03: compile-time error
 
   makeFoo() {
     // Box.T is not assignable to num.

Same again.

+    return new Foo<T>(); //# 04: compile-time error
   }
 }

Same again: `String is not a subtype of num`.
