Why isn't + and the basic arithmetic operators defined as multimethods in Clojure?

Question

Performance concerns perhaps?
Or not to encourage questionable operator overloading bonanzas?

Cool, thanks!

Yes, all the choices around math ops are performance related. Operator overloading was not considered a big concern.
