Good point... You can subclass them. Problem is this is how they work: Consider
db.table.field.something() db.table.field is a Field with Extends expression "something" is a method of Field or Expression and delegates to self.table.field.db._adapter.SOMETHING(....) which performs the action. So adding a feature is not as easy as extending or subclassing a class. Most actions involved two or more classes. Implementing a new feature requires two steps: - adding an API at the web2py layer (Field, Expression, Rows, etc). - adding a translation for each supported adapter (they all extend BaseAdapter).
