| * @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 p < n and m == q then T0 is not a subtype of T1 |
