like BoundCompoundPropertyModel, but safer. i think this almost might be too
clever as it sacrifices some intuitiveness. also, it's filling in for a
missing java feature. this should really be:
boundModel.bind(component, firstName.property)
(where .property, .field and .method are long-missing declarative
reflections like .class)
it does make me think we could be doing more with CGLIB in general. our
model classes ought to be able to detect model changes better using proxies,
for example.
