Well, every object in a patch has a name.  To find that object, the tree
of patches and scopes is crawled upward from the site of the lookup. For
example, the (equivalent of) [s "foo"] first looks in the scope of the
[s], then the patch-global scope of the containing patch, then in the
application global scope for the name "foo". 

Dotted notation can drill down, so [s "foo.bar"] would try to find an
object named "foo", then find "bar" in its patch-global scope (or an
object named "bar" within a scope named "foo" in the current patch). 

Does that make sense?
