It looks natural, but .bind(to:) is kinda misleading in the context. I would suggest dispose(when:).

[ikesyo]

Hmm using the same word dispose may be a bit confusing:

producer.start().dispose()
// versus
producer.start().dispose(when: lifetime)

[andersio]

I think it is a reasonable mental model. If you don't specify anything, it is disposed of immediately. If you specify whenEnded, it is disposed of at a certain point in the future.

[ikesyo]

whenEnded sounds good (over just when).

[sharplet]

What about dispose(atEndOf: lifetime)?

[mdiep]

Do you think this is still needed now that += is back?

[ikesyo]

I'm happy with += so withdraw this.
