I don't remember any such cleanup, and searching my online copies of the passed
proposals has failed to find one.
I do remember this question being discussed some time ago. I think the
discussion took place on this (the clos) list, and was triggered by Moon
mentioning a recent extension added to Symbolic's implementation to permit
something like what Chris describes. My recollection is that such a thing was
considered reasonable, but it may have never gone beyond that (ie. maybe nobody
ever got around to bringing this up for x3j13 to consider).
