[SQLObject] a third way of accessing attributes

[Bud P. B. <bu...@si...>]

Some time ago, Nick and Ian (and others?) discussed about two ways of
exposing SQL data through object attributes:

* metaclasses (current SQLObject) that set properties
* __getattr__ and __setattr__

There seems to be a third way:

* Adding methods and properties (attributes) to a class at runtime 
  (sans metaclasses).  

The advantage I see (yet to be verified) is that this approach allows
a very weak coupling of application objects with the backend
implementation:  

There doesn't even seem to be the need to inherit from some "storable"
class or similar (SQLObject).  Instead, when the Backend is
initialized, it simply loops through all ObjMaps in the Mapping and
adds attributes and methods accordingly.  I kind of like this...

For who is interested in more details, I attach a little test that
demonstrates this.
