I am playing GIRepository with G::O::I.
I get a GIRepository::BaseInfo object from gir get_info funtion.
One question is how to test whether this object is a GIRepository::CallableInfo.
And another question is how to cast this object to a GIRepository::CallableInfo.
GIRepository::BaseInfo is the base class of GIRepository::CallableInfo, and the latter further has multiple derived classes.
