 * @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, ... ,

 *
 *  and T1 is U1 Function<Y0 extends B10, ..., Yk extends B1k>(S0 y0, ...,

 *  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]
