Description
#general > where is `Lean.ofReduceNat` used?
#new members > Where is the axiom `ofReduceNat` used? @ 💬
ofReduceNat is currently unused in Lean 4 and Mathlib but may be used in the future. Also note that if you were to delete the axiom the entire mechanism around ofReduceNat should be deleted as well which requires touching some kernel code etc.

Research direction
Start by reading the linked Zulip discussions about Lean.ofReduceNat and search the Lean 4 and Mathlib sources for references to it. The issue notes that removal would also require deleting the surrounding mechanism and touching kernel code, but it does not define whether that work is wanted or what completion entails.
