You may be interested in the Actor Model [1] computation style. When used for programming, it looks like a programming paradigm where functional and object-oriented styles are neatly supported and blended without any impedance mismatches. Most code is written in a functional style, but there are abstractions that encapsulate state changes and make it work together with the mostly declarative functions. There are at least a couple of Coursera lectures teaching this style (one about programming paradigms, the other about reactive programming), it's worth giving it a look.
