The title definitely does seem like click bait to me, as I went to the source and looked for where it said that and it does say that the Malbolge language (a Lisp dialect) is "almost impossible to use". Does that mean that Common Lisp is "impossible"? No, it doesn't, therefore that is why I think the title is click bait.

> Malbolge is a public domain esoteric programming language. It was specifically designed to be almost impossible to use, via a counter-intuitive 'crazy operation', trinary arithmetic, and self-modifying code.
