Actually, as a user of Gecode, I had remained sofar completely oblivious
to these design oddities.  However, I have been developing a new family
of constraints, and, as an implementor, I have to make design decisions.
I went to the existing code for guidance and I got confused: it didn't
seem to follow a very clear design paradigm.  That's why I asked.  Also:
is there a downside to providing the most general templates?
