| * @assertion A type T is more specific than a type S, written T << S, if one of the following conditions is met: |
| * - T is S. |
| * - T is ⊥ |
| * - S is Dynamic. |
| * - S is a direct supertype of T. |
| * - T is a type variable and S is the upper bound of T. |
| * - T is of the form I<T1, ..., Tn > and S is of the form I <S1, ..., Sn> and Ti << Si 1 <= i <= n. |
| * - T and S are both function types, and T << S under the rules of section (Types/Function Types). |
| * - T is a function type and S is Function. |
| * - T << U and U << S. |
| * T is a subtype of S, written T <: S, iff [⊥/Dynamic]T << S. |
| * A type T may be assigned to a type S, written T <=> S, if either T <: S or S <: T . |
| * @description Checks that unrelated generic types are not assignable even if all their type arguments are. |
