Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR ensures info tree users such as linters and request handlers have access to info subtrees created by async elab task by introducing API to leave holes filled by such tasks. **Breaking change**: other metaprogramming users of `Command.State.infoState` may need to call `InfoState.substituteLazy` on it manually to fill all holes. |
