It is rarely used. Of my 39 test Schemes, only Racket, Gambit, Larceny, IronScheme, Shoe, and and XLisp do something other than error out as soon as they see #" -- but in most of these cases, I don't know what they are actually doing. > Given that eggs will be > broken, whichever way the working group decides, I believe it is better > to reduce the amount of special characters to allow maximum flexibility > for naming in the identifier lexical space. On the other hand, Racket, Gauche, MIT, Gambit, Chicken, Bigloo, Kawa, SISC, Chibi, Chez, Ikarus/Vicare, STklos, KSi, Rep, Oaklisp, and Owl Lisp all understand |...| syntax. Scsh, Guile, SCM, NexJ, Shoe, TinyScheme, Dream, Scheme 7, BDC, Elk, UMB, VX treat | as an ordinary identifier character. Scheme48, Larceny, Ypsilon, Mosh, SigScheme, RScheme, XLisp, Schemik all report syntax errors. IronScheme gets hung up reading characters from the input. -- John Cowan [email protected] http://ccil.org/~cowan If I have not seen as far as others, it is because giants were standing on my shoulders. --Hal Abelson _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
