Nice to see it's finally in!

However, I have to report a _tiny_ feature of applying your function:

When run on a buffer containing:

    #+property: var  foo=1

    #+begin_src emacs-lisp
     foo
    #+end_src

    #+results:
    : 1

it will translate `#+results' to `#+name':

    #+property: var  foo=1

    #+begin_src emacs-lisp
     foo
    #+end_src

    #+name:
    : 1

Further evaluations of that *un-named* code block will leave the `#+name'
line.

To get back the expected `#+results' line, you have to manually remove that
results line, and re-evaluate the code block.

Best regards,
  Seb
