Common Lisp, at least, isn't about functional elegance. It's mostly an imperative language with some functional constructs for convenience. Indeed, it probably has the best iteration facilities of any moderately popular language.
Yet the definition of Lisp is as elegant as it gets. And it potentially has the best of everything, thanks to real macros.
No, it isn't. There's a difference between McCarthy's "Maxwell's equations of software" and the full-blown Common Lisp standard, which was designed by and aimed at industry.
It's still there, it's perfectly possible to not use all the stuff they piled on top. At least it's useful, semi coherent stuff; as opposed to C++.
