On language side, suspending functions provides an abstraction for asynchronous operations while on library side kotlinx.coroutines provides functions like async { } and types like Flow. Spring laziness is not needed, fun handler(mono: Mono) becomes fun handler(value: T) since a suspending functions can be invoked to get the value parameter. • If laziness is needed, fun handler(mono: Mono)
