----------------
This is where lambda would have some advantage as we could capture what it needs without having to pass 'this' or 'E' explicitly.
In this case it's not too bad, so I'm fine either way, with a very slight bias towards lambdas. The static functions just don't seem to buy us anything here, IMO.
