dont know but <g> let me try yet another attempt at rephrasing this. suppose you ask an intermediate beginner how 5--4 would be parsed, as: a) 5 - -4 b) 5 -- 4perhaps he does not need to look up the chapter in the pharobook and will choose b). but if he looks into the pharobook he will read under "Binary messages": "Note that −− is not allowed for parsing reasons" (i just checked the latest version) now honestly, dont you think that a) is a serious contender? that is all i wanted to say.
