What about noweb instead?

# Hide drawers when the document is opened
# to not be distracted by intermediate evaluation
# results that are duplication of original code.
#+startup: overview

# (require 'ob-org)

# Default ob-org settings are not suitable for code examples.
#+property: header-args:org :exports code :results replace :noweb yes

# Not necessary when ":exports results" is used for intermediate blocks.
# #+options: d:(not "noexport")

You may include code blocks in your documents.

# This one is actual example of code.
# It is not exported, but it may be easily edited using C-c '.
#+name: code-example-elisp
#+begin_src elisp :exports none :results silent :var a=()
  (identity a)
#+end_src

# This one is for exported document.
# To evaluate during export ":exports both" is set.
#+name: code-example-org
#+begin_src org :exports both
  ,#+name: code-example
  ,#+begin_src elisp :var a=10
  <<code-example-elisp>>
  ,#+end_src
#+end_src

:noexport:
# Hide duplicated code block inside a drawer.

# Ensure that elisp code (result of org block evaluation)
# is evaluated as well by ":exports results"
#+header: :exports results
#+results: code-example-org
#+name: code-example
#+begin_src elisp :var a=10
(identity a)
#+end_src

# Empty line above is important to keep :end:
# when the code of the org block is re-evaluated.
:end:

To get result of code evaluation
#+results: code-example
: 10
use =C-c C-c= while cursor is inside the code block.
