let's take a different POV: even if you work with classes, where should you
store your "objects", and with what ?
web2py ships with DAL that is not an ORM like in other frameworks. The
"classes" paradigm can be adopted too but it's usually an extra step that
can be beneficial only in huge apps with lots of business logic. If in the
end you're going to store your "objects" in a table using DAL, you're just
back to square one ^_^
