By idempotent-when-possible, I mean to_bytes(str_or_bytes, encoding, errors) that would pass an instance of bytes through, or encode an instance of str. And of course a to_str that performs similarly, passing str through and decoding bytes. While bytes(b'abc') will give me b'abc', neither bytes('abc') nor bytes(b'abc', 'latin-1') get me the b'abc' I want to see.These are trivial functions; I just don't fully understand why the capability isn't baked in.
Possible reasons: They are special purpose functions easily built on the basic functions provided. Fine for a 3rd party library. Most people do not need them. Some might be mislead by them. As other have said, "Not every one-liner should be builtin".
