I am probably old-fashined, but I always prefer to stick to ASCII unless there is a compelling reason. If I want something to stick out, I can always customize Emacs to do it. Also, I don't think it is ideal to have two (or more) operators that are interchangeable as far as the language is concerned, but have stylistic differences assigned to them by convention. If that convention is useful and justified, it should be merged into the language per se; if not, then it just borders on confusing. Best, Tamas
