A notable group of exceptions to all the previous systems are Interact — Lisp (programming language)

"By policy, LISP has never really catered to mere mortals. And, of course, mere mortals have never really forgiven LISP for not catering to them."

"(What the world needs (I think) is not (a Lisp (with fewer parentheses)) but (an English (with more.)))"

"Some said the world should be in Perl, Some said in Lisp. Now, having given both a whirl, I held with those who favored Perl. But I fear we passed to men A disappointing founding myth. And should we write it all again, Id end it with A close-paren."

"Lisp has jokingly been called "the most intelligent way to misuse a computer". I think that description is a great compliment because it transmits the full flavor of liberation: it has assisted a number of our most gifted fellow humans in thinking previously impossible thoughts."

"Pascal is for building pyramids -- imposing, breathtaking, static structures built by armies pushing heavy blocks into place. Lisp is for building organisms -- imposing, breathtaking, dynamic structures built by squads fitting fluctuating myriads of simpler organisms into place."

"DOLIST is similar to Perls foreach or Pythons for. Java added a similar kind of loop construct with the "enhanced" for loop in Java 1.5, as part of JSR-201. Notice what a difference macros make. A Lisp programmer who notices a common pattern in their code can write a macro to give themselves a source-level abstraction of that pattern. A Java programmer who notices the same pattern has to convince Sun that this particular abstraction is worth adding to the language. Then Sun has to publish a JSR and convene an industry-wide "expert group" to hash everything out. That process--according to Sun--takes an average of 18 months. After that, the compiler writers all have to go upgrade their compilers to support the new feature. And even once the Java programmers favorite compiler supports the new version of Java, they probably still cant use the new feature until theyre allowed to break source compatibility with older versions of Java. So an annoyance that Common Lisp programmers can resolve for themselves within five minutes plagues Java programmers for years."
