Well I'll contend it is at least ambiguous because I read it differently. :) I think everyone can agree that keywords begin with a colon. My understanding is that symbols and keywords share naming rules as a result of "Keywords are like symbols". I think the interpretation depends on whether you see the ":" as being part of the name; I would say not (that's how keywords are represented in print form but the : is not stored or returned as part of the namespace or name). Symbols and keywords share the same symbolPat regex in LispReader with I believe the same intent for allowed names. > I am frightened that opinions differ; especially Rich's, obviously. > I think at this point it is unlikely that "keywords starting with numbers" are going to become invalid (and I would like to formalize that in the reader page). Even if the reader could not read them, keywords (intentionally) can be created that cannot be read by the reader via the "keyword" function and this is a widely used feature. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
