/**
 * @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 the static type of function literal of the form

 * (T1,...,Tn, [Tn+1 xn+1,...,Tn+k xn+k]) -> Future <flatten(T0)>.
