Sometimes I think it would be nice to have a way to draw property values
directly into a babel block, the way you can with table data. Sort of
like:
* Heading
:PROPERTIES:
:ID: 3f78f08a-ccca-4fc0-aba9-2a192f7a0e5a
:foo: 5
:bar: puppy
:END:
#+BEGIN_SRC emacs-lisp :var alist=3f78f08a-ccca-4fc0-aba9-2a192f7a0e5a
And in the block, the "alist" variable would look like '(:foo 5 :bar
"puppy").
What would be even better would be to run a tags search on matching
headlines and feed all property drawers into a single block, as a list
of alists. Just thinking out loud...
