Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR fixes `ST.Ref.ptrEq` to act as described in the docs. This fixes two bugs: 1. The recent `IO.RealWorld` elimination PR overlooked this function (afaik this is the only one), causing its return value to be generally wrong. 2. The implementation of `ptrEq` would previously always consider two different cells with pointer equivalent value to be pointer equal. However, the function is supposed to check whether two `Ref` are the same cell, not whether the contained elements are. |
