A big one is persistent data structures. Where 'persistent' may not mean what you think it means. In Clojure it is impossible to surgically modify a data structure. That is, you can't do something like: (SETF (CAR (CDR x))

The article asserts that authors are not testing their code. The problem is that you can't ensure that every possible bug is exercised in tests. Think of the static typing of the compiler as the very first level of testing. If you c

Marketing seeks to destroy the meaning of useful technical jargon. The term Operating System is a good example. Most people have no idea what an OS actually is. They think it is all of the stuff bundled with the OS. Similarly in the 1980&
