Yeah I mean I for one am over ten years old so I remember when 'functional' pretty much just meant functions-as-first-class-values and every-thing-returns-a-value. Then because those are pretty reasonable language features all the languages that had been written in the late 80s-mid 90s and became popular around 2000 had those features. So then for a while 'functional' was just sort of way of saying 'not java'. Now 'functional' seems to mean strong algebraic typing for some reason.
