Yes, this is a perfect example of when to employ the anchor pattern. It's
also a perfect example of the bug we need to fix in puppet.
Class foo, bar, an baz will "float off" in the relationship graph because
class wrapper contains no other resources to "anchor" them down.
If you add a begin an end anchor resources to class wrapper and establish
relationships between them and the three contained classes, it should work
as you expect
I will give a concrete example, if you wish, once I get to my desk.
