It's impossible to get people to agree on what OOP is exactly, but almost everyone agrees that hiding/isolating mutable state (inside objects) is an essential part of it. Just google "what are objects in programming".

Totally agree that these paradigms are badly defined. See my other comment where I explain it more https://news.ycombinator.com/item?id=34217547

My point here was that all "OOP" languages (that I know) allow you, with all their "OOP feautres", to work with objects which actually don't contain any mutable state.

I'll let you be the judge whether it is still "OOP", but I know from experience that it's very practical for Software Engineering.
