Peter Dalgaard responded:   

Actually, this is the easier fix to my mind. Where do you see the danger?

To which I reply:

Well, if it's feasible, I'd recommend this as the way to go. My detached
phrase "Sorry folks, too dangerous" was simply my wondering how we might

field the inevitable howls of protest when people find that something has
changed. I know people will notice since this is a glych I spotted when

trying to debug someone else's code, but that person, at least, will applaud I'm sure.

In short, I don't think there are any real dangers. I just thought it would slow things down too much, but perhaps not.
