Agreed. I took a year (long ago) to learn lisp just to be exposed to a different way. And it has paid dividends in terms of providing alternate ways of thinking about code in other languages. That said, I'd never want to use lisp in a real production project. Same for FP. Get exposed to these things, take the learnings and bring them into KISS boring production code that is fast and maintainable.
