Hi Anthony

No it was more stuff like `return' and `return-from'.

OK, I understand. I managed to slowly integrate (some of) your changes.
It should now generate milestones for nodes that cannot be scheduled and
are leaf nodes. So basically it should export valid code for tj3 if you
set org-export-taskjuggler-target-version to 3.0. Of course the report
definitions in the defcustom org-export-taskjuggler-default-reports are
not compatible with tj3 so you will need to change these.

I have (or I guess rather had) some fondness for recursive functions, so
I re-implemented your leafiness function recursively. However I ran into
problems with max-lisp-eval-depth and it appears that recursion is not
encouraged in Emacs lisp
So I guess it's back to iterative style.

I like the drawer stuff and will integrate it.

Absolutely, I agree.

Hm, no this is not possible right now. Why would you want to do this?
Maybe we could just mark it as a comment and make the exporter honor

I set up a repo and pushed my changes to the code there

Yes, I almost forgot. Would you mind doing that?
