Ahh seems so obvious now, I should have noticed. I was surprised though:

(defun my-test-defun
  "This is a test"
  (message " in my test"))

(defun my-test-defun2 ()
  "This is a test"
  (message " in my test 2"))

You can happily C-x C-e eval-last-sexp both of those defuns without
complaint. The error in the defun only shows up when you try and execute them.
