thanks, that works !

I still have a question, though:

The reason I missed that was that in my real code I initialized the class_<>
with a no_init argument, as that was declared to be the way to make the (C++)
class non-instantiable. However, even though I only want subclasses to be
instantiated, I of course do need to initialize the base class (i.e. run
its constructor).

How should I do that, then ?

Thanks again,
