Objects/descrobject.c:1050:19: warning: cast between incompatible function types from ‘PyObject * (*)(mappingproxyobject *, PyObject * const*, Py_ssize_t)’ {aka ‘struct _object * (*)(struct <anonymous> *, struct _object * const*, long int)’} to ‘PyObject * (*)(PyObject *, PyObject *)’ {aka ‘struct _object * (*)(struct _object *, struct _object *)’} [-Wcast-function-type]
 1050 |     {"get",       (PyCFunction)mappingproxy_get,        METH_FASTCALL,
      |                   ^
