React does this (at least the escaping of output part). Bunch of PHP frameworks do it too. But I think it's just a natural part of the power of computers, except most people don't think in Lisp ("any" text could be turned into code), they think in Java (I have this static, rigid, compiled code, and that's the only thing that runs).
