Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR changes the Lake DSL to use builtin elaborators, macros, and initializers. This works out of the box for the Lake executable and is supported in interactive contexts through the Lake plugin. |
