Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.

This PR adds infrastructure for parallel execution across Lean's tactic monads. - Add IO.waitAny' to Init/System/IO.lean for waiting on task completion - Add `Lean.Elab.Task` with `asTask` utilities for `CoreM`, `MetaM`, `TermElabM`, `TacticM` - Add `Lean.Elab.Parallel` with parallel execution strategies: * `par`/`par'` - collect results in original order * `parIter`/`parIterGreedy` - iterate over results (original or completion order) (also variants with a cancellation token) * `parFirst` - return first successful result This does *not* attempt to be a monad-polymorphic framework for parallelism. It's intentionally hard-coded to the Lean tactic monads which I need to work with. If there's desire to make this polymorphic, hopefully that can be done separately. |
