I'd be surprised if it wasn't. This is immediately obvious to anyone who's tried to solve practical problems in languages, rather than just learned them for resume embellishment purposes. That's also why sane companies limit the languages that can be used for development: if you let your "theoreticians" run wild, you will soon end up with code written in Brainfuck and Malbolge using libraries no one understands. I'm exaggerating, obviously, but only slightly.
