In fact, it does not inherit from Exception::Class. Exception::Class
is not a classical class itself after all but offers via its import
function to define subclasses of Exception::Class::Base.
My module installs functions because I see an exception as something
that belongs to a package. However, I already thought about also
offering an mk_exception_methods function for people who prefer to
throw an exception with a method call.

Well, the reason against that is the mk_exception_methods function I
just mentionend. But I had not thought of using import, it's a nice
idea.
Thanks for your feedback,
