Right, thanks -- good thing I clearly posted it was a sketch and untested;-). In practice it's no doubt better to mark the function as being abstract (e.g. with a function attribute) and otherwise leave it alone; people who are keen about abstract classes and methods often want to be able to call such abstract methods explicitly (for dubious reasons, but it _is_ a common practice in C++, for example -- make a method pure virtual, and yet give it a body anyway, for the benefit of subclasses' overriding-methods).
