No (because class instances aren't functions, although they can masquerade
as one.. in this case it's just not worth it).  You really want to make a
Product.  External methods are most useful for short functions, and they get
really awkward when you combine them with classes due to security assertions
that need be made, pickleability of class instances, and other things that
can bite you.  In short, don't.  ;-)

No problem...
