I had't seen it! The "clones" feature is cool, it sounds like they're way ahead in figuring out how to use transclusions effectively when coding.

Previously I'd thought of using transclusions for things like long-lived documentation. Now reading about Leo it seems like they'd be just as useful for creating short-term views into one's code. Eg start a refactor PR by transcluding all the relevant definitions into a doc. Now you can start writing PR comments in that doc before you even begin coding, and when you do all the relevant code is right there.
