// 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)

// See https://github.com/pybind/pybind11/pull/3497 for full context.
// NOTE: This workaround knowingly violates the Python.h include order
//       requirement (see above).
