Are Clojure keywords with the same name guaranteed to be identical? i.e. Is (identical? :a :a) guaranteed to return true?
What are the precise rules when the keywords of the same name are in different namespaces? For example, (identical? :a ::a) is false. Why?
Keywords which are = are guaranteed to also be identical?, and those which are not = are of course guaranteed to not be identical?.
:a is different from ::a because the latter has a namespace component and the former doesn't. How could they be identical? Identical means, the very same object reference. Since they have different characteristics they cannot be the same object.
