Subject: [PATCH] Base: templates for type checking

=================================

Original idea of Werner:
https://github.com/FreeCAD/FreeCAD/pull/10643#issuecomment-1712966545

I really liked this syntax to avoid repetition and even explicit consideration of Types when type checking.

I thought it would be a pitty to get it lost.
