What are the reasons for this change? (If it is changed I think we should call it bimap.above)
I like the above view because the set of relations is handy (and better suited) for general not directed task such as insertion (it is more efficient in it than in the side views), iteration, questions as size or empty. Why not to make it easily accessible?
If you want to know the size and there is not such thing as the relation view, what side would you choose? bimap.left.size()? What is special about it? bimap.size() is IMO a better way to express in the code your intention.
First off I confess that I'm not completely set on this change - just that it's one possible solution to a recurring theme among reviewers. The rationale is that it forces you to specify *which* view you're talking about. Maybe an alternative would perhaps be to document bimap from the start as a "container of relations that also offers left/right associative views". BTW "above" is a terrible name: call a relation a relation IMO :-) John.
