This raises an issue I've been running into recently, If I have a
multi-line elisp function (I guess same issue would apply for multi-line
shell commands) that I want to use from an org file (for example to
compute table columns), is there a way to save and load the function
from the org file? I've tried multiline [[elisp: ]] links but they
don't work well, maybe something like...
[[eval-source]]
#+BEGIN_SOURCE elisp
#+END_SOURCE
Thanks -- Eric
