We use `no_index` to work around special-handling of `OfNat.ofNat` in `DiscrTree`, which has been reported as an issue in https://github.com/leanprover/lean4/issues/2867 and is currently in the process of being fixed in https://github.com/leanprover/lean4/pull/3684. As the potential fix seems non-trivial and might need some time to arrive in-tree, we meanwhile add the `no_index` keyword to the problematic subterm. --------- Co-authored-by: Eric Wieser <wieser.eric@gmail.com> |
