It would be even nicer if we didn't need a mixin for classes that
simply forward the ctor call to the base class ctor:

class FileException : Exception { }   // no-go, have to write a ctor
that forwards to super

AIUI this has something to do with ctors not being virtual. I think
someone mentioned this could be improved one day.
