Code review comment for lp:~james-w/lazr.restful/object-unmarshal

I agree with Gary. It's problematic that we have two different criteria for deciding whether a field name should end in "_link" or "_collection_link" or nothing at all, and a branch that fixed that would go into lazr.restful. But this problem should be fixed in Launchpad, and though I don't totally understand Gary's proposed solution it seems like the kind of thing Launchpad needs.
