i really appreciated the paper and as someone who has spent many years deciphering what the author calls 17th century-style proofs am completely aligned with the objective and the method. i personally find myself doing a version of what the author proposes (in private notes) to make sure i understand proofs i read in books or papers.
even so it would have been timely, useful, and relevant to include a comparison to proofs in lean by comparison to TLA+ even though it is not Lamport’s personal project.
