Exceptions is a good thing. But I'd like to see benefits of having this handler. I am not against it, I simply want to see purpose before it is made :) You know, every feature should have some kind of idea behind it :) So, benefits are:
1. ....
2. ....

I definitely see this handler as central function with a way to call user functions inside. Logging extensions is a good candidate for hooking into exception handler. So it should be a bit more sophisticated than create_function ;)
