Yes absolutely. I recently added by accident Lattice_Syntax somewhere in the Library and a lot of AFP theories (and HOLCF) broke down at unexpected places. Alternatively: Would a lattice_syntax locale work nowadays? I remember I tried it once and for some reason it didn't work. Either notations aren't supported in locales or they are exported after the context -block. - Johannes _______________________________________________ isabelle-dev mailing list isabelle-...@in.tum.de https://mailmanbroy.informatik.tu-muenchen.de/mailman/listinfo/isabelle-dev
