The 2-arity Keyword.intern method and clojure.core/keyword fn should be left intact, so as to provide an escape hatch for those that really do need colon-prefixed keywords.</p> CLJ-463

Strip leading colons when creating keywords from single strings

If I say (keyword "::foo"), what am I asking for? I almost wonder if this should throw an exception.</p> <p>I think (keyword "::foo") (and any more leading colons) should fail, and this patch should only strip one colon.</p> <p>Updated patch forthcoming.</p> <p>After thinking about this for a while, I've now reversed my position, and am in favor or retaining the current functionality. Thanks for the pushback.</p> <p>As for throwing exceptions on colon-prefixed, un-namespaced keywords, I'm not certain that that's a good idea. People use keywords to hold all sorts of data, use them as map keys and lookup fns, etc.</p> Global Rank
