<p>Nope, there is no more elegant way. And you'll probably need to walk the class tree using ParentClass and retrieve each name.</p>
<p>Note: an except-handler will suffer from the same problem if it needs to catch an exception that was raised from the library (or the other way round).<br>
You are going to a extreme fragile direction there.</p>
