note: in places where i suggested `PyValue&` instead of `MlirValue` we need to be cognisant of the issue I ran into here: https://github.com/llvm/llvm-project/pull/176299, namely that lvalue reference and `nb::rv_policy::automatic` decays to `nb::rv_policy::copy` for [lvalue refs](https://nanobind.readthedocs.io/en/latest/api_core.html#_CPPv4N8nanobind9rv_policy9automaticE).
