Coroutines are one of those things that are hard to understand and you
can go for years without ever having a use case for them, but then one
day you find a need for them and they make all the difference in the
Certainly they're not STRICTLY necessary, as it's always possible to
use closures and state machines to implement the same functionality,
but when they're the right tool for the job then having them supported
at the language level makes them much easier to work with and reason
about than the alternative.
