> I sometimes would hit walls, because in real world software, you need persistent state. Functional software, for obvious reasons, fights against that, and so modeling state is actually quite difficult. I haven't felt this, Clojure has good primitives for dealing with state, both temporary and more permanent. The biggest difference from (most) mainstream languages is that it's very explicit what has state and where you're mutating it. But personally I feel like that makes it easier to manage complicated state relationships, rather than harder, since it's typically isolated in smaller parts.
