Thanks a lot Howard! Indeed, I should have know, since one week ago I
read (enjoying it a lot!) Herb's paper on ADL... ;) I should really
double check and read it again together with your message (now I'm
running out for a few hours, sorry) but I gather that Herb's
modifications would avoid these trickeries, right?

Paolo.
