Re: \ \ \= are valid in symbols?
The docs say what characters are guaranteed future-safe for *you* to use in symbols, nothing more. I don't see what's so puzzling about this.

According to: http://richhickey.github.com/clojure/clojure.core-api.html The following are symbols using those characters: - - = = == = not= : (used in condp) As per the discussion last week, all the characters not listed in the reader page were free-game for potential reader-macro use. Is it really still an open question that these comparison functions would be changed in order to make those characters into macro characters? If not, can the reader page be updated?

Oh yeah, we should fix the reader page to acknowledge that we've used these characters in symbols already The reader already has a macro associated with \, the character literal. user= (int \) 62 user= (str \) user= (first ) \ HTH, Sean On Apr 5, 11:19 am, Douglas Philips d...@mac.com wrote: On 2010 Apr 5, at 3:49 AM, ataggart wrote: The docs say what characters are guaranteed future-safe for *you* to use in symbols, nothing more.

Not \ or \ etc. Well, I was/am trying to be precise. Symbols are looked up by strings and strings contain characters, unlike some languages (Python, say), where characters are just single letter strings... user= (seq =) (\ \=) Sorry for the confusion! -Doug -- You received this message because you are subscribed to the Google Groups Clojure group.
