| * @assertion Two objects T1 and T2 which are instances of Type (that is, |
| * runtime type objects) are considered equal if and only if the runtime type |
| * objects T1 and T2 corresponds to the types S1 and S2 respectively, and the |
| * normal forms NORM(S1) and NORM(S2) are syntactically equal up to equivalence |
| * of bound variables and ignoring * modifiers on types. |

| * only if the runtime type objects T1 and T2 corresponds to the types S1 and S2 |
| * respectively, and the normal forms NORM(S1) and NORM(S2) are syntactically |
