As a rule of thumb, don't return objects you didn't create inside a

Unless its job is specifically to get/fetch an object (reference

then it should probably not mutate the object before returning the
reference.
I wish I'd had that advice when I started learning python. It would have
saved me no end of grief.
I wish I had seen this 'rule' before too.
