I didn't say there were ONLY two ways. In fact I expected there'd be at least some ways involving calling Java APIs on some Clojure objects such as namespaces, though mucking about in the guts like that is even more perilous (and, particularly, prone to break when Clojure changes its internals). How stable is the intern function likely to be? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
