Ok: then how is the - at compile time unknown - state of a closure different from the state kept in an objekt? That you have to look for the the value outside the lexical context is part of the intended behaviour and noone who can write closure would be surprised or expect a different behaviour. I think your argument is a little bit trampling on a strawman. Correct me if I'm wrong, but it seems you are claiming FP would promise a much simpler behaviour, by deliberately misunderstanding FPs design principles. There is a clear difference between constructing closures and mutable variables, even if the behaviou of a function/closure is determined non-(source)-locally at runtime. If somebody exaggerated or misrepresented FP to you, thats not FPs problem, but yours, because you obviously seem to know better
