If you'd like to read more, an excellent introduction to the Common Lisp condition system is given in Practical Common Lisp: http://www.gigamonkeys.com/book/beyond-exception-handling-co...
And I wrote a tutorial on Common Lisp restarts, using them in a non-trivial real world example: http://chaitanyagupta.com/lisp/restarts.html
NSColor * color = [Colors h00FF00];
The post probably should've mentioned reader macros, since this is how you do this sort of stuff "normally".
This was something I really loved during my time in Common Lisp. This was a gem that I was hoping would make it into Clojure, but I think around version 1.3 they decided to abandon the idea and add a library to "make anything throwable" which totally missed the point in my opinion. Are there any other languages that allow the calling scope to specify how lower-level functions handle errors without unwinding the stack…

Any language with continuations can have it added as a library. Of course, not a lot of popular, non-Lisp languages these days have continuations... (Ruby kinda does -- it was a language-level feature in 1.8 but has been sidelined since as non-MRI implementations generally don't support them.)

For conditions in Clojure check out Ribol: http://docs.caudate.me/ribol/
though honestly Ribol is probably a better bet---just wanted to show that this kind of thing can be done as a library without too much complication.

Perl 6 allows for handling exception in a same-scope CATCH block, so you can try to recover. It can probably be mixed with their phasers[1] in interesting ways. Also of interest might be control exceptions[2]. 1: http://perlcabal.org/syn/S04.html#Phasers 2: http://perlcabal.org/syn/S04.html#Control_Exceptions
"It's not Lisp!"
It's nice seeing Common Lisp posts on the front page.
Yes, even if the industry usage is not big, learning about other languages is always a good way to improve our skills.
