+A mixin class that injects a suitably named logger into class scope
+at runtime.
+
+Chosen to make this a slotted class, which means (as far as I can remember)
+that it is not suitable to be made into an abc.ABC class. Slots will
+enable derived slotted classes to be a bit more efficient at runtime and
+boast faster lookups.
