I was trying to start with the the intended behavior of the str class, then move on to generalizing to other classes, because I think completing a single example and *then* generalizing is an instructional style that's easier to digest, whereas intermixing all of the examples at once can get confused (can I call str.removeprefix(object(), 17)?). Is something missing that's not already there in the following sentence in the PEP?
Although the methods on the immutable ``str`` and ``bytes`` types may make the aforementioned optimization of returning the original object, ``bytearray.removeprefix()`` and ``bytearray.removesuffix()`` should always return a copy, never the original object.
