Yeah - pure functions and immutable data aren't always the right answer, but appreciating that they're damn good most of the time is a good first step. Writing obvious code that does exactly what it appears to do at first glance and not one thing more? Your colleagues will thank you when they have to work with your stuff.

I’m sorry to hear you learned nothing.

And metaprogramming and tail call optimization and and…. At least other languages are starting to catch up with this 60 year old language, by for instance implementing lambda expressions.
