On this topic, how do primitives work? I heard something about "function boundaries." Which I interpret to mean that when a function returns a primitive, Clojure boxes it in some Java object. And type declarations can't stop this boxing from happening.
Is this a correct understanding? (I doubt it is, since it leads to odd conclusions.) And what is the performance penalty here? (I'm not personally concerned about performance, just curious.)
