Ah ok I understand what you are trying to say now. I understand that.
I think the article does a poor job of explaining this (actually I don’t think they explain that at all) so thanks for the help on that.
I do understand the usefulness (albeit I’m not sure how OFTEN this would come up? I’ve managed everything so far without the need for this but I can imagine situations which this would have been useful) that Jeet is offering here. Thanks!
I wasn’t trying to insinuate I had conflicting views. Merely stating that I failed to see the authors point (again, because no explanation was given so I was left to imagination.) I actually do see your point and agree there are cases where this is useful.
