Sorry if I was unclear: I'm not loading org-element-ast.el or using it
directly; I have just adopted the same basic format for iCalendar syntax
nodes. This should make it easier to switch to org-element-ast.el
if/when it eventually becomes a more generalized library. But at the
moment, there are enough feature differences that I don't think that
makes sense.

I was not aware of peg.el, and it doesn't seem to be installed in my
(Debian-built) Emacs -- find-library does not find it. Is it new? Where
can I take a look at it?

Best,
