 * @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]) sync* {s} is
 * (T1,...,Tn, [Tn+1 xn+1,...,Tn+k xn+k]) -> Iterable.
 * 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]) sync* {s}
 * with two parameters is assigned to a variable of a function type with two
 * parameters that do not correspond to function literal parameters.
