// STRONG REQUIREMENT:
// This header is a wrapper around `#include <Python.h>`, therefore it
// MUST BE INCLUDED BEFORE ANY STANDARD HEADERS are included.
// See also:
// https://docs.python.org/3/c-api/intro.html#include-files
// Quoting from there:
// Note: Since Python may define some pre-processor definitions which affect
// the standard headers on some systems, you must include Python.h before
// any standard headers are included.
// To maximize reusability:
// DO NOT ADD CODE THAT REQUIRES C++ EXCEPTION HANDLING.
// Disable linking to pythonX_d.lib on Windows in debug mode.
#if defined(_MSC_VER) && defined(_DEBUG) && !defined(Py_DEBUG)
// Workaround for a VS 2022 issue.
// See https://github.com/pybind/pybind11/pull/3497 for full context.
// NOTE: This workaround knowingly violates the Python.h include order
// requirement (see above).
