"C" Enums have ordering but not hash defined

See #3557 - it looks like we automatically implement ordering but not hashing for C-style `#[pyclass]` enums. This is almost certainly an oversight. One straightforward option is to just add...

Users may appreciate a document comparing PyO3 against approaches like uniFFI and cffi, and maybe even Cython and pybind11. (This would focus on the extension module case, we could do...

After #3358 these are the remaining uses of `AsPyPointer`: - [ ] `Py::is` - [ ] `PyAny::is` - [ ] `PyVisit::call` - [ ] `impl FromPyObject for Py` #3358 holds...

Supporting PGO builds from `maturin`

In `pydantic-core` we have been building with PGO for x86_64 Windows and Ubuntu for some time, and we're now also looking at GitHub's new M1 runners to run PGO optimization...
