The first statement concers the Clojure *reader*, which parses source code according to the rules specified in the link provided. What I think the first quote refers to, is that all tokens that begin with a ':' will be parsed by the reader as Clojure keywords and not symbols. Additionally a colon at the end of a token is indicated as invalid so it should result in an error.
Here are the three cases that I can make out form the documentation, tried at the Clojure REPL: *user=>* ':with-colon :with-colon *user=>* (class ':with-colon) clojure.lang.Keyword *user=>* 'sym:bol sym:bol *user=>* (class 'sym:bol) clojure.lang.Symbol *user=>* 'symbol: RuntimeException Invalid token: symbol: clojure.lang.Util.runtimeException (Util.java:170) The document on the second link states at the beggining that* "A superset of edn is used by Clojure to represent programs"*,so it would make sense that edn takes into account the usage of ':' in symbol names. I don't think it's an inconsistency since it doesn't concern the reader, but the *symbol* function that takes a string and returns a * clojure.lang.Symbol* doesn't seem to have any issues with the trailing colon or other read-invalid symbols, you can basically throw any string to it and it'll return a *clojure.lang.Symbol*. *user=>* (symbol "symbol:") symbol: *user=>* (class (symbol ":symbol")) clojure.lang.Symbol Hope it helps, Juan On Sunday, February 24, 2013 9:13:13 PM UTC-3, Alexander Krasnukhin wrote: > > Hi, > > I'm confused.
