Hi all -- I'm not sure if I missed it, but does Moose explicitly model the <<creates>> relationship of UML between two classes, e.g.,
Based on http://themoosebook.org/book/index.html#h1thefamixfamilyofmeta-models I found Entity -> SourcedEntity -> Association -> {Access, Invocation, Inheritance, Reference}. In Moose, I can see outgoingInvocations on methods of a class contain "new X" for all the X that a class creates, but I wondered if there's a more efficient way. 

Cheers!
