I thought that this example:
NewProject = Project.owner.address.city = "Boston".
clashes with existing syntax. How about:
NewProject = Project.owner.address{city = "Boston"}
Because you can perfectly well do this today:
X = Y = 17
which binds both X and Y to 17.
You may also want to think about how it clashes with packages
(if it does - I can't come up with an example at the moment.)
Otherwise, I like the idea.
BR,
