| * @assertion The function type (T1, ... Tn, {Tx1 x1, ..., Txk xk}) -> T is a subtype of the function |
| * type (S1, ..., Sn, {Sy1 y1, ..., Sym ym }) -> S, if all of the following conditions are met: |
| * 1. Either S is void, or T <=> S. |
| * 2. For all i 1 <= i <= n, Ti <=> Si. |
| * 3. k >= m and yi belongs to {x1, ..., xk} for each i in 1..m. |
| * 4. For all y in {y1, ..., ym}, yi = xj => Tj <=> Si |
| * @description Checks that function type t1 is not a subtype of function type t2 |
| * even if just one of t1's named optional parameters has a type that is not mutually assignable with |
| * the type of t2's corresponding named optional parameter. |
