As some people have pointer out Common Lisp is one of those languages. I
don't know anything about language design, I'm just a hobbyist
programmer, but I think Common Lisp's condition system and its restarts
are straight-forward and easy to understand from programmer's point of
view.

Here's the relevant chapter in Peter Seibel's Practical Common Lisp:
