I rapidly see when I get an answer like that that it's all well outside what I will ever do myself, BUT knowing what people are doing or trying to do or wanting to do or not able to do, and why (in all the cases and flavours), is 'all good stuff". I absolutely guarantee I could not pass a test on that, but having read it, enough will hopefully have hidden itself in the dark recesses of my brain well enough that the content addressable search engine will be able to pull out enough fragments at some unknown future date to allow me to know where I read about it. Hopefully. A lot of the stuff that my brain stores seems to end up being a lot more useful to other people than it ever is to me :-).
