I wondered if that's what was meant... hence the last para of my
message, and my comments in my follow-up to Quentin Anciaux. But you
explain it better (in a bit I snipped!).

Mind you, I don't understand why you find your definition "attractive". It
would be pretty confusing for physicists to say "there's only one
electron", even though they all are absolutely identical.

And also, as I mentioned to Quentin, if you are going for such a radical
first-person perspective, an OM really *has* no outside so it is a bit
misleading to talk of "pasts" at all.
