Source: Simula Research Laboratory (Mr. Bran Selic, selic(at)acm.org)
Nature: Uncategorized Issue
Severity: 
Summary: It seems possible to draw associations between any two kinds of types, including seemingly absurd combinations of associations between, say, an Interface and a Collaboration.Should there be constraints that prevent such combinations? If not, then the semantics of such combinations should be clarified.
