Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR extends the behavior of the `sync` flag for `Task.map/bind` etc. to encompass synchronous execution even when they first have to wait on completion of the first task, drastically lowering the overhead of such tasks. Thus the flag is now equivalent to e.g. .NET's `TaskContinuationOptions.ExecuteSynchronously`. |
