Declarative programs are easier to work with since they only express computation logic without complicating the code with control flows. Such programs also have fewer unclear procedures, implicit dependencies andmutablestates, which also simplifies programming. ...
I have looked at the stateful generation features, but I don't actually want to test a mutable interface in my properties, I want to make use of state during generation. I actually don't mind if that is done via a mutable or immutable interface, I just need a way to thread that stat...
