Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
@kha I implemented a more complex example for the paper. The difference in performance is awesome. On my Linux desktop: Lean time: 3.34 secs OCaml time: 11.72 secs I believe that the difference in performance is due to destructive updates happening in transformation functions such as `reassoc` and `const_folding`. I will add a flag to Lean to disable `reuse/reset` automatic insertion. BTW, this test requires `ulimit -s unlimited` to avoid stack overflows. |
