Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
When elaborating the headers of mutual indexed inductive types, mvars have to be synthesized and instantiated before replacing the fvars present there. Otherwise, some fvars present in uninstantiated mvars may be missed and lead to an error later. Closes #3242 (again) |
