Cool, thanks! I don't build from source, but I look forward to that support in the future. You can see how SLIME (the Common Lisp emacs support library) does it here <https://www.youtube.com/watch?v=sBcPNr1CKKw&list=PL2HCA9vU95bsKlhegE6-_Wiks3EpzXuoF&index=4&t=593>. I use mostly IJulia these days, and I don't see a clean mechanism for integrating it in there, but Jupyter is moving at a steady pace, so maybe in a few releases. The main use for Emacs' macroexpand is to understand how a complex macro works in a given piece of code, and to debug new macros. The ability to selectively macroexpand and contract specific portions of the tree is important. Best, Cédric
