Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
aa5b392e35
This PR fixes a kernel type mismatch that occurs when using `grind` on goals containing non-standard `OfNat.ofNat` terms. For example, in issue #9477, the `0` in the theorem `range_lower` has the form: ```lean (@OfNat.ofNat (Std.PRange.Bound (Std.PRange.RangeShape.lower (Std.PRange.RangeShape.mk Std.PRange.BoundShape.closed Std.PRange.BoundShape.open)) Nat) (nat_lit 0) (instOfNatNat (nat_lit 0))) ``` instead of the more standard form: ```lean (@OfNat.ofNat Nat (nat_lit 0) (instOfNatNat (nat_lit 0))) ``` Closes #9477 |
