The closest I've got to functional programming is SQL and that has often made me fear for my sanity.
Perhaps functional programmers have travelled through a black hole and out the other side into hell and end up as some unnatural human-functional code merged construct, like in the Disney film of the same name*. They don't make them like that any more.
* The Black Hole, not that whole sentence.
