Well, it depends on your point of view. According to the most respected Computational Theologian of our time, rather a lot of the universe is written in Perl [1]. Is Perl "functional programming"? One might argue it at least embeds a functional programming language within itself, but I suspect if we could do exegesis on the phrase "hacked most of it together in Perl" that it would not very strongly suggest the sort of elegance one nominally associates with Functional Programming.
