Thanks folks. I appreciate it I guess logically I understand it and have before but I feel like I have some intuitive gap/resistance to really accept this (because I feel like I have run into this before).
In the spirit of Haskell, it would be interesting to have a Maybe type to wrap the List type. So Maybe List could return a list, a single char or a list with a single num, or an absence of both. http://learnyouahaskell.com/a-fistful-of-monads The return type of insert_at is a list and so technically this works fine, but folks just have a lot of programmer word gravity and baggage -- LOL. So even though '\a' is in fact [7] which is a list, `\a` in itself printed out doesn't look like a list. Just my 2 -- Enjoy the Olympics!
