* @assertion A type T0 is a subtype of a type T1 (written T0 <: T1) when:
* Positional Function Types: T0 is U0 Function<X0 extends B00, ... ,
* Xk extends B0k>(V0 x0, ..., Vn xn, [Vn+1 xn+1, ..., Vm xm])
* and T1 is U1 Function<Y0 extends B10, ..., Yk extends B1k>(S0 y0, ...,
* Sp yp, [Sp+1 yp+1, ..., Sq yq])
* and p >= n
* and m >= q
* and Si[Z0/Y0, ..., Zk/Yk] <: Vi[Z0/X0, ..., Zk/Xk] for i in 0...q
* and U0[Z0/X0, ..., Zk/Xk] <: U1[Z0/Y0, ..., Zk/Yk]
* and B0i[Z0/X0, ..., Zk/Xk] === B1i[Z0/Y0, ..., Zk/Yk] for i in 0...k
* where the Zi are fresh type variables with bounds B0i[Z0/X0, ..., Zk/Xk]
* @description Check that if T0 and T1 satisfies the rules above, then T0 is
* subtype of T1. Test the case when p > n and m > q.

* @description Check that if type T0 is a subtype of a type T1, then instance
