Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
The implementation is good enough for implementing extensible parsers, elaborators and tactics, but there are a few TODOs 1- We should have a better story for standalone applications. Most of them don't need `evalConst`, and the global table is just initialization overhead. 2- The global table introduces a dependency on the `Lean.Name` implementation. So, all standalone applications will depend on it. 3- We are not storing arity 0 constants in the table. This one should be easy to fix in the future. |
