I'd agree with this and add that pattern matching and functional interfaces are additional examples of tools from the FP toolbox being subsumed into existing programming languages.

Pure functional programming seems tempting. In small projects it can produce beautiful, readable code. In large projects I've only seen it result in messes, and I still haven't decided whether that's due to limitations of functional purity, due to the team (and myself) misusing features that we don't understand, or both.
