Maybe they should both print as > "Foo.baz"? Since lexically scoped is the normal situation perhaps it should get the ordinary Foo.baz syntax and the dynamically bound variables should get the other syntax. Actually, for non-qualified variables there is still no syntactic difference between dynamically and statically scoped ones so it begs the question of why a syntactic difference is needed for the qualified case (or perhaps if a syntactic difference in the non-qualified would be a good idea).
