From the little bits of dabbling with various lisps in have done a functional language is different enough from my bill paying regular languages (JS, php, Java) that without a focused study on a project that hits several layers of a typical stack, I fully expect the language to be foreign to me. Until I know the 350 core language operations by heart I'll not be able to play with them. If I cannot play I'll never be able explore the language and use and misuse it until I can make it do what I want it to do.
So the fact that it looks encrypted to you is a good thing. It's a code waiting for you to break it. It's a problem waiting. A small group of extremely intelligent people are responsible for the family of lisps. That tells me that if/when I do dedicate the time and effort to understanding the lisp tools it will be worth the effort.
