Instead devolving responsibility for second > guessing their intent to such as I and they. First, that's such a weak pillar which remains on which to base all your cl-lib.el fury. Hair-splitting over a word and and bringing up a dictionary definition written more than 100 years ago when programming was basically non-existent. And did you see my reply to Tomas where I listed that at least 5 other programming languages use the same word (or at least the '-' operator) for the same operation? There is indeed such a thing as set theory in mathematics and the literature uses that term to refer to that operation. What a bad idea it would be for Elisp to stray from that practice just so your argument can stay afloat. Jo=C3=A3o
