> Mmm, I think it's a huge stretch to say those languages were derived from Lisp I did want to say that. I said 'Most other languages, derived from Lisp, are incompatible' - that means the languages which were derived from Lisp - like Scheme, Logo, Dylan, Clojure, partially JavaScript - those are incompatible. Like Ruby, which was either influenced or in the same application niche (web programming, scripting, ...) like Perl is incompatible with Perl. There is a similarity: Lisp -> lots of incompatible dialects Scripting languages -> lots of incompatible languages But Lisp has with Common Lisp as standard, which has enable many different implementations with different capabilities, but a large shared core language.
