/**
 * @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]) => e is
 * (T1,...,Tn, [Tn+1 xn+1,...,Tn+k xn+k]) -> T0, where T0 is the static type
 * of e.
 * In any case where Ti, 1 <= i <= n + k, is not specified, it is considered
 * to have been specified as dynamic.
 * @description Checks that a static type warning occurs when assigning a
 * function literal of the form
 * (T1 a1,...,Tn an, [Tn+1 xn+1 = d1,...,Tn+k xn+k = dk]) => e
 * to a variable whose type is not a function type.
