It's not really a bug, neither a feature that might be concerned by feature freeze so I reported as bug. I think it should be implemented before release so the new functionality could be used by all.
In the new Function Editor tab in expression dialog, there are three icons that IMO should offer information about what they do when hovering them. It's not really obvious to all of us.
