Thanks for pointing me to this! I took a look at the file commentary,
and I've played around with org-element before. I do like org-element's
plist-based format...it makes things simple and readable as an outside
tinkerer.

Can you tell me a bit more about the performance benefits? Do these
mostly just stem from the use of an array for :standard-properties?
(You get this for free with cl-structs, too.) Or is it more about when
and how parsing happens? (This is something I feel like I've never
grasped in org-element...in the past I've been confused because the
properties I'd see when calling e.g. org-element-at-point would be
different than the ones available in some other context.)

Thanks!

Best,
Richard
