Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
The array read and write operations are now called: - "Comfortable" version (with runtime bound checks): `Array.get` and `Array.set` like OCaml. It is also consistent with `Ref.get` and `Ref.put`, and `get` and `set` for `MonadState`. - `Fin` version (without runtime bound checks): `Array.index` and `Array.update` like in F*. - `USize` version (without runtime bound checks and unboxing): `Array.idx` and `Array.updt`. cc @kha |
