/// @assertion We say that a type T0 is a subtype of a type T1 (written T0 <: T1)

/// Right FutureOr: T1 is FutureOr<S1> and
///   either T0 <: Future<S1>
///   or T0 <: S1
///   or T0 is X0 and X0 has bound S0 and S0 <: T1
///   or T0 is X0 & S0 and S0 <: T1
/// @description Check that if a type T1 is Future<S1> and a type T0 is X0 and
/// X0 has bound S0 and S0 is not a subtype of Future<S1> or S1, then a type T0
