I'm admittedly nitpicking here, but I think "(non-)imperative" is not a useful label for characterizing Lisp-ish languages. Some Lisps, like Clojure, are rather functional; others, like Common Lisp, are considered imperative.

For the distinction you're looking for, I'd like to suggest "C-like" or "Algol-family" instead for those languages which work with sequences, conditionals, loops and probably braces and semicolons.
