We already have disagreement, as indicated by the various R5RS implementations, as to whether case-folding in ASCII identifiers is the right thing or not. (I say "two or more" because there are two kinds of diacritics in Vietnamese, those that mark tone and those that distinguish separate vowels. The former are thought of as diacritics, the latter as part of the vowel letter, just as the dots in ä (a-diaeresis) and ö (o-diaeresis) are in Swedish -- but not German.) For that matter, I note that while the non-normative section 2.1 of R5RS says: The precise rules for forming identifiers vary among implementations of Scheme, but in all implementations a sequence of letters, digits, and "extended alphabetic characters" that begins with a character that cannot begin a number is an identifier. In addition, +, -, and ... are identifiers. the formal syntax in 7.1 prescribes a fixed syntax for identifiers that does not permit any such "extended alphabetic characters." -- Evolutionary psychology is the theory John Cowan that men are nothing but horn-dogs, http://www.ccil.org/~cowan and that women only want them for their money. http://www.reutershealth.com --Susan McCarthy (adapted) jcowan@xxxxxxxxxxxxxxxxx
