这是具有深层方法S的类的示例。

class Core {
    read = () => true
}

class Customer extends Core {}
class Plan extends Core {}

class S {
    stripeCustomer = new Customer()
    stripePlan = new Plan()

}

type a = ReturnType<Core['read']> // boolean
type b = ReturnType<S['stripeCustomer']['read']> // boolean

这是我正在寻找的语法：

DeepMethodReturnType<A,B>

type c = DeepMethodReturnType<S,'stripeCustomer.read'>

是否可以使用点表示法访问类的深层方法？像stripeCustomer.read一样？
