* @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] | |

* 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 | |
