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
