I think Ruby has a super interesting middle ground. It’s strictly OOP in that everything is an object or a method (or a block), but because of implicit method calls (no parens), implicit return values, ease of use creating anonymous blocks passed to methods, and meta programming allowing dynamic control flow (i.e. calling a method by name at runtime), it has a lot of the elegance of writing functional code. You end up with small, unit-testable, methods that you can chain together, concise syntax, and meta programming that is second only to Lisp macros. It feels a little bit like if you asked a functional programmer to design an OOP language.
