From 2a2ce21a09bb2e42589777069593b8dda802125e Mon Sep 17 00:00:00 2001 From: Emilio Jesus Gallego Arias Date: Thu, 27 Aug 2020 19:22:07 +0200 Subject: [declare] Fix types of mutual lemmas when using Admitted. We fix a clear coding mistake in 79bcf1c0a22e736c4e2cae3460c35b3d9fca9aa0 that forgot to update the type of the parameter entry when saving mutual definitions without a body. We follow the solution suggested by Hugo Herbelin and drop the type used in `start_proof`. Note the duplication here indeed.
