* @assertion A type T0 is a subtype of a type T1 (written T0 <: T1) when:

*
* 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} subset of {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]
