I just don't see the point, except as an academic exercise

The point is partly academic, as I am working on learning MPL. However, I think that this technique, or some derivation thereof, can help make code more maintainable, since you can reuse my_exception_handler whenever you want to handle the same exception in the same way, even though you catch it in a different place. With catch blocks the only recourse, so far as I can tell, is to basically copy-and-paste the catch code to each location where you need the exception handling code.

This is true. Though I personally tend to use macros for this specific instance.
