// Macro to use C++ static_cast<>, reinterpret_cast<> and const_cast<>
// in the Python C API.
//
// In C++, _Py_reinterpret_cast(type, expr) converts a constant expression to a
// In C++, _Py_CAST(type, expr) converts a constant expression to a
// non constant type using const_cast<type>. For example,
// _Py_reinterpret_cast(PyObject*, op) can convert a "const PyObject*" to
// _Py_CAST(PyObject*, op) can convert a "const PyObject*" to
// "PyObject*".
//
// The type argument must not be constant. For example, in C++,
// _Py_reinterpret_cast(const PyObject*, expr) fails with a compiler error.
// _Py_CAST(const PyObject*, expr) fails with a compiler error.
