I can imagine wanting to eager load attributes and relationships under
certain circumstances, for example the N+1 query problem. If all loads were
lazy I'd always get N+1 queries to load N beans. If I could configure it
for eager load then I could also load N beans in 1 query.
Cheers

No, but I'd be interested in hearing what other behaviors you would
envision?
