Interception.listen

Listen for any exceptions raised.

The listener block that you pass in will be executed as though inside Kernel#raise,
so your entire program is still actively running. If you have a gem like
pry-stack_explorer you can access the stack frames that lead to the exception
occurring.

NOTE: Be careful when writing a listener, if your listener raises an
exception it will mask the original exception (though it will not recursively
call your listener).
