 * @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* {s} is
 * (T1,...,Tn, {Tn+1 xn+1,...,Tn+k xn+k}) -> Stream.
 * 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* {s}
 * with two parameters is assigned to a variable of a function type with the
 * same parameters and Future return type.
