Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR makes `simp_arith` use `RArray` for the context of the reflection proofs, which scales better when there are many variables. On our synthetic benchmark: ``` simp_arith1 instructions -25.1% (-4892.6 σ) ``` No effect on mathlib, though, guess it’s not used much on large goals there: http://speed.lean-fro.org/mathlib4/compare/873b982b-2038-462a-9b68-0c0fc457f90d/to/56e66691-2f1f-4947-a922-37b80680315d |
