I was trying to make a point without starting a flamewar that was beside the point. Personally I’d never choose a dynamically typed language for a production system. That being said, Python and Ruby complain if you try to add an array, dict/hashmap, string, or number to another (of a different type) so they’re certainly more sane than JavaScript.

Any of them which are still strongly typed. Just because a language doesn't check for type errors before runtime doesn't mean it won't check at all

Lisp?
