"Alan Gauld" <alan.gauld at btinternet.com> s'exprima ainsi:

While this is probably true for _single_ objects in most case, I guess it really makes sense to create a common structure for object collections. Eg Position, with x & y attributes, for a very simple case. But indeed there are complex ones, possibly with nested structures such as eg Point inlcluding position, color,...
In addition, doing this helps readibility by clearly exposing the object (type) structure in a single & visible place.

All of this applies both to "value" objects (pure information, such as a position) and "real" objects (distinct things, such as a point).
What do you think?
