> When using pyarrow interface from a c++ library one will get the following compiler warning:
> {quote}{{warning: 'unwrap_table' has C-linkage specified, but returns user-defined type 'arrow::Status' which is incompatible with C [-Wreturn-type-c-linkage]}}
> {{ARROW_EXPORT Status unwrap_table(PyObject* table, std::shared_ptr<Table>* out);}}
> {quote}
> This is due to a Cython artifact.
