Things worth looking at can be weird in various ways. APL and J show interesting ways of using layout to bind together capable and compact primitives, in a way that avoids naming intermediates. Forth shows another interesting way to connect together primitives and calls, but it also shows how simple a powerful language can be to implement. Haskell shows you how the structures of higher mathematics can be directly used in programming. Clojure shows you how a language can embed the concept of time in distributed systems, and how immutability is compatible with change. Lisp shows you how a program can comprehend its own representation.
