Thanks. I had a quick look, but I could not see an immediate improvement 
over my current setup.

I just did a quick inventory of my Field class, which is an abstract class.

I have 13 datatypes, therefore 13 subclasses. I have 26 methods which are 
common to all subclasses, so they are defined on the Field class.

Each subclass has between 5 and 10 methods declared on that subclass. Some 
of them do not exist on the Field class, as they are all different. Some of 
them do exist on the Field class, as only some of the subclasses require an 
override, the rest can use the generic method.

This arrangement has evolved over time, but has now settled down and is 
stable.

It is just a slight annoyance (to me) that pylint complains about the 
subclass methods when they are called from the Field class. I don't mind 
adding 10 stub methods to the Field class to keep it happy, but I do not get 
the feeling that it is improving my code. I do grant, however, that it may 
be of benefit to someone reading my code for the first time.
