Great example, thank you! I found I had to call `button.enable_interrupt().unwrap()` inside the loop, or I'd only get precisely one interrupt. This is noted in the most recent docs for `subscribe()` where they note that you must call it from non-ISR context.

Thanks for reading! To your comment, there has probably been a change in the interface, however, it makes sense. Resetting the interrupt enable is not unusual.
