I worked on this for several days at the end of last year. My approach was
simple: make Perl_croak_sv() turn exception strings into full-blown exception
objects with the string as the payload. After some work faking up a new
package ('CORE::Exception'), I flailed around with overload magic for a while,
and never quite managed to get everything all working together to the point
where enough of the test suite passed successfully that I could diagnose what
went wrong.
In retrospect, the worst part was probably trying to manage a new Perl class
(well, namespace and methods and overloading) from XS. Loading it from a .pm
file wasn't any better, as you can imagine that introduced introducing
bootstrapping issues.
I can't find the relevant branch at the moment, but I'm not sure there is much
left salvaging at this point.
