Do flyweight patterns exist in coroutines?

For example, let's say I have 5 suspend methods that require a parameter, which can also be retrieved by a suspend method.

If I call two of them simultaneously, is there a way for me to have them wait on the same suspension?

One way of doing this would be to keep a map of keys to deferred values, where I assume that calling await twice will only run the logic once. Is there a better way of achieving that?

That's literally what you get by using `async` and then calling `await()` on the same deferred object

If you do a Lazy dispatched `async` you can spawn them all off immediately and then the `async` won't start until the first `await()` invocation
