True. Then again, it wasn't valid R5RS either, or R4RS or even R3RS; R2RS was the only Scheme standard to explicitly allow it, almost thirty years ago. The theory of R7RS identifiers is that they can't have a prefix which is a valid number. In practice, many Schemes simply attempt to parse an alphanumeric sequence as a number, and if that fails, accept it as an identifier. -- John Cowan http://www.ccil.org/~cowan co...@ccil.org Consider the matter of Analytic Philosophy. Dennett and Bennett are well-known. Dennett rarely or never cites Bennett, so Bennett rarely or never cites Dennett. There is also one Dummett. By their works shall ye know them. However, just as no trinities have fourth persons (Zeppo Marx notwithstanding), Bummett is hardly known by his works. Indeed, Bummett does not exist. It is part of the function of this and other e-mail messages, therefore, to do what they can to create him. _______________________________________________ Scheme-reports mailing list Scheme-reports@scheme-reports.org http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
