I've heard that argument before -- it came up during the C++ standardization process. Beware, because the committee ended up making choices just like what's being proposed here, and I don't think anybody was truly happy with it. They just couldn't agree on anything better. > I'd suggest therefore a means of extending the "named" characters -- > R5RS gives us #\space and #\newline but we ought to be able to add > characters to the named set using some kind of binding construct, and > thereafter refer to them by name in strings, character constants, and > identifiers. C++ works like that. You can write identifiers directly in Unicode, or you can mangle them like that. The idea was that editors could hide the mangling from you, or convert to and from it, but I'm not aware of any editors that actually support that. It's a kludge, and people would much rather just use characters than use this kind of markup. (I could have a biased impression of the user experience with this, because I personally dislike it, just so you know.) -- Bradd W. Szonye http://www.szonye.com/bradd
