Hi Eric,
Thanks for the feedback. You are right that this could be more
extensible. I’m attaching a new version of patches #2 and 3 to this
email, which should be an improvement on that front. I also added
docstrings, and a test.
Aaron
PS You were right about org-every vs. mapcar in your other message.
