This might seem strange, but first thing that jumps out about this
example is the "style" doesn't feel right. Or at least it doesn't feel
consistent with sqlobject. Maybe something more like this:
class MyForm (widgets.Form):
age = widgets.TextField(
default=0,
validators=(
validators.Int(min=4, max=12),
validators.Required())
I still need to read about formencode, so I'm not sure if my list of
validators even makes sense. Now that I think of it, composition (ala
composite pattern) would probably beat lists for testability anyway.

Smart! I like it.

Hmm. I really need to go read about formencode.... (going now :)
