I also suggest making all bytes literals immutable to avoid running into any issues like the above.

+1 from me.

Rather than adding immutability to bytes objects (which has big implementation and type checking implications), consider using buffer(b"123") as an immutable bytes literal. You can freely concatenate and compare buffer objects with bytes objects.

I like Georg's idea of having an immutable bytes subclass. b"abc" could then be a shortcut constructor for this subclass. In general, I don't think it's a good idea to have literals turn into mutable objects, since literals are normally perceived as being constant. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, May 05 2007)
