+# Problem!
+# our existing scripts/jig driver, the name of the mux is the
+# class of the virtual mux. This scheme below will not allow that
+# to work.
+# Assuming an existing script with a mux called NewVirtualMux
+# 1. Update every reference in the script
+#    dm.jig.mux.NewVirtualMux -> dm.jig.mux.new_virtual_mux
+# 2. Change the class name, but keep the attribute name
+#    @dataclass
+#    class JigMuxGroup(MuxGroup):
+#        NewVirtualMux: _NewVirtualMux
+#    Then the references in the script stay this same.
+#    jig.mux.NewVirtualMux
+# 3. Change the attribute name on mux, like in the example below,
+#    but add some compatibility code to MuxGroup base class so that
+#    attribute lookups that match the Class of one of its attributes
+#    get magically mapped to the correct attribute.
