Another possibility would be, to use a temporary variable with lexical scope

(let ((tmp (* (+ 1 2) (+ 3 4))))
  (defun test () tmp))

or even a global variable:

(setq tmp (* (+ 1 2) (+ 3 4)))
(defun test () tmp))

This is not exactly the same as having a read-time evaluation of the expression, since it adds a variable dereferencing 
at run-time to the code. But it gets pretty close.
