/// A Subject is something that is an Observable and Observer (Subscriber) at
/// the same time. Signals pushed into it will be received by the subscriptions
/// made from it, broadcasting them.
///
/// Subjects do not actually implement [SubscriptionLike][crate::SubscriptionLike]
/// despite them having an `unsubscribe` method and being closable.
/// The reason is that subjects do not and can't own resources, that's the job
/// of the subscriptions you make with them. This allows subjects to be safely
/// droppable without having to call `unsubscribe` on them even in a
/// [DropUnsafeSubscriptionContext][crate::DropUnsafeSubscriptionContext].
/// The `unsubscribe` method on subjects is only there for users to mass
/// unsubscribe every subscription made from the subjects.
