* @assertion A type T0 is a subtype of a type T1 (written T0 <: T1) when:
* Named Function Types: T0 is U0 Function<X0 extends B00, ..., Xk extends B0k>
* (T0 x0, ..., Tn xn, {Tn+1 xn+1, ..., Tm xm})
*
* and T1 is U1 Function<Y0 extends B10, ..., Yk extends B1k>(S0 y0, ..., Sn yn,
* {Sn+1 yn+1, ..., Sq yq})
* and {yn+1, ... , yq} subsetof {xn+1, ... , xm}
* and Si[Z0/Y0, ..., Zk/Yk] <: Vi[Z0/X0, ..., Zk/Xk] for i in 0...n
* and Si[Z0/Y0, ..., Zk/Yk] <: Tj[Z0/X0, ..., Zk/Xk] for i in n+1...q, yj = xi
* 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 there is i in 0...n such that
* Si[Z0/Y0, ..., Zk/Yk] is not subtype of Vi[Z0/X0, ..., Zk/Xk], then T0 is not
* a subtype of T1. Test generic types
