SharedGeometry.__eq__
=====================

.. py:method:: t3toolbox.shared_geometry.SharedGeometry.__eq__(other)

   .. code-block:: python

      def __eq__(self, other) -> bool:
          # type(self), NOT the hardcoded class: a SUBCLASS is a different geometry, and this pair is a jit
          # cache key (a SharedGeometry rides in GaussNewtonModel's aux). Hardcoding the name made a
          # subclass with different math compare and hash EQUAL to the plain wrapper, so whichever was
          # compiled first served both -- a silent wrong answer for the un-subclassed object.
