Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR modifies the "issues" grind diagnostics prints. Previously we would just describe synthesis failures. These messages were confusing to users, as in fact the linarith module continues to work, but less capably. For most of the issues, we now explain the resulting change in behaviour. There is a still a TODO to explain the change when `IsOrderedRing` is not available. |
