Hi!
I'm thinking about architecture of multiplatform library. For example we have expect class `Client`. This class should have a lot of code for all platform, but difference is in method to make (for example) HTTP request. Currently I have `AbstractClient` class with common code  and `expect class Client : AbstractClient` (actual classes implements platform dependent stuff). Is this good architecture? Or maybe should I make delegate all platform depended stuff to separate classes and use "plain" `Client` class?

Another problem (related to previous): I have `Request` class. Responses are handled asynchronously, but in JVM (and only in JVM) implementation I want to have method `getResult()`, what works synchronously (waits for result).

How architecture, design patterns should I use for that?
