An alternate `defmacro2` definition with compile time semantics

;; An alternate `defmacro2` definition based on the example from
;; "Macros are Hard" presentation by @david_mcneil. This
;; implementation defines a macro called `name` and a function
;; equivalent called `name+` which still evaluates at compile time as
;; opposed to execution time
(defmacro defmacro2 [name args & body]
  `(do
     (defmacro ~name ~args ~@body)

     (defn ~(symbol (str name "+")) [~@args]
       (~name ~@args))))

(defmacro2 foo [a b] `(+ ~a ~b))

(foo+ 1 2)
