> Let's face it - it's not the language that is the problem. It would help you, but it would help you only with some percentage of the problems out there.

Let's not underestimate the help that a language can provide; writing interpreters for languages is almost trivial on a lisp because you can reuse pretty much every piece of machinery on a lisp for your ends. Similarly, there is an entire class of problems that is nearly trivial on prolog that is pretty difficult to get right on other languages simply because prolog makes it easy to express rules and specifications that need to be met. Just look at an implementation of a sudoku solver in prolog and compare it with some other language.

I feel that a language designed with concurrency in mind would make it much simpler to write an entire class of problems. These languages are just gaining traction, so we are yet to see bigger and more significant examples. However, the "ants.clj" demo that Rich Hickey has written in Clojure, and some of the erlang demos in Joe Armstrong's book have made me a believer.
