I like Smalltalk squeak's continuation solution for handling exceptions.
It works well for programming errors, doesn't clutter your code and allows to reproduce the exact environment in which the error happened (making it much simpler to understand the problem).
Regarding external failures, it works fairly well too (although I agree something better can surely show up) since you can use the variant type to obtain data about the error and insert it into the normal behavior of your software (like you do on Java or similar others).
Finally, when it comes to user input errors, it is clear to me that it is NOT an exception (more like a rule) and should be handled as part of the normal flow of your software and exceptions been used for such are usually a bad smell!

Anyway, thanks for the post. Good stuff to think about.
