Yeah I think I glossed over this aspect a bit as it looks ostensibly like simply reinstating a helper function because the code is now used in more than one place (at lsf/mm so a little distracted :) But it being exported is a problem. Perhaps there's another way of acheving the same aim without having to do so?
