 |  __eq__(self, right)
 |      Return self==value.

 |  __repr__ = _dumps_object(klass)
 |      Overwrite default string output for any wrapped object.
 |      By default, __repr__ method returns something like:
 |      <OCC.Core.TopoDS.TopoDS_Shape; proxy of <Swig Object of type 'TopoDS_Shape *' at 0x02BB0758> >
 |      This is too much verbose.
 |      We prefer :
 |      <class 'gp_Pnt'>
 |      or
 |      <class 'TopoDS_Shape'>
