By saying "reference counting is a form of GC", I'm not sure whether or not you think that reference counting has usage outside of (and could have predated) GC.

By saying "reference counting is a form of GC", I'm not sure whether or not you think that reference counting has usage outside of (and could have predated) GC. David did not write "a form of" either, although you think the meaning conveyed is the same. Also one could also counter similarly with saying that if David meant should, he would have said so, but whatever. I realize memorymanagement.org conflicts with my usage, although I'm not sure I subscribe with the idea that the usage people have been using first historically is sensible.
