Lightweight Wrappers for Conscious std::transform_reduce Operation Safety
summary
Prototype library shim pstl::algorithm requires explicit commutativity annotations for operations used with parallel std::transform_reduce and uses C++20 compile-time checks to refuse compilation when the user hasn’t asserted commutativity. The claim is that axiomatically trusting small, user-provided guarantees is far cheaper than trying full automatic verification; a student-built lightweight prototype already prevents common noncommutative mistakes and the code is slated for public release.
