These are all part of the most basic functions of list. A subclasser should know that.
They are different from swap() which is an optimization hack that breaks encapsulation
and is not a basic function of lists. The docs are fine as-is.
Adding esoterica to the docs tends to make the docs harder to digest
and less useful to people trying to learn the language.
