There was a problem hiding this comment.
@infinisil This warning message is not 100% correct in this case. Because either has nestedTypes.left and right not elemType. Should we change the message to use nestedTypes.* instead ? (Leave out the last part because different types might use different attribute names)

Alternative design thoughts:
How about using named functor.payload attributes instead of
elemtType. In this case.leftand.rightwhich would help to remove using list indexes.Since this PR changes the type it would be a good opportunity to also change the internal representation in one go.
