What does tar mean? ls? df? gunzip (something with guns?)? Every language old enough will assemble some naming problems. If you look at newer languages, even there naming is still the old problem. Clojure: What does fnext do different than nnext? Can you guess what rseq does? With larger software systems, you'll see that you will need to look up documentation quite often. On my old Lisp Machine there are 60000+ symbols naming tens of thousands functions. So naming becomes important. When Lisp was small, there were functions which print something, then variations were added and people tried to keep the names short. After a while there were so many functions and memory was larger. People started to use longer names. CALL-WITH-CURRENT-CONTINUATION (in Scheme) or SET-DISPATCH-MACRO-CHARACTER were the results. ;-) Now we got nice descriptive names, but we need completion during input. There is no way other than to learn a certain base vocabulary. Since the printer is essential in Lisp, you'll need to learn functions like princ or print to read older code. In your own code you can just use WRITE, which is a general interface into the printer. Fortunately enough, the documentation of these functions is just a keypress away in any good Lisp implementation. |

How are MORE bad examples an argument against what he says? If anything they reinforce his statement.
Plus, the thing with "tar" and "ls" is that they've been tar and ls in all Unices for decades. If you learn "ls", and maybe "dir" if you want to use Windows, you're golden. Whereas every language seems to use its own names for "princ", "setf" etc, both before and after CL.
