| * @assertion The static type of a function literal of the form |
| * (T1 a1,...,Tn an, [Tn+1 xn+1 = d1,...,Tn+k xn+k = dk]) async => e is |
| * (T1,...,Tn, [Tn+1 xn+1,...,Tn+k xn+k]) -> Future <flatten(T0)>, where T0 |
| * is the static type of e and flatten(T0) is defined as follows: |
| * If T = Future<S> then flatten(T) = flatten(S). |
| * Otherwise if T <: Future then let S be a type such that T << Future<S> and |
| * for all R, if T << Future<R> then S << R. |
| * In any case where Ti, 1 <= i <= n + k, is not specified, it is considered |
| * to have been specified as dynamic. |
| * @description Checks that it is a compile error if a function literal of |
| * the form (T1 a1,...,Tn an, [Tn+1 xn+1 = d1,...,Tn+k xn+k = dk]) async => e |
| * with two parameters is assigned to a variable of a function type without |
| * parameters. |
