Okay. CS Weenie, if you’re reading this: I tried lisp in more than just a trivial application and you’re right.
I find Closures more fun (and useful) than I feel comfortable admitting around my friends. Stacks and trees are trivially easy. Calling functions (like this) took some getting used to, and occasionally I’d find myself slipping back to my C roots but overall I’d have to concur that there are programs that can only be written in Lisp.
I haven’t had much of a chance to play with the really meaty code-as-data stuff or macros yet.
I haven’t forgotten my Church-Turing: Lisp is just as powerful as any other language at the machine level, but the Lisp solution to a problem always seems a bit more elegant (not to mention shorter.)
Oh, and Nyquist is based on lisp. Bonus points are awarded for advanced synthesizer languages.
