It's only obvious in the sense that _after_ you see this idiom, you can go back to the docs and
realize it's not doing something special; OTOH if you haven't seen it, it's not at all the obvious
solution to "how do I get the first 256 characters". So IMO it should be mentioned, given that
string.translate often operates on the identity table. I think a single sentence is adequate for the
reference docs.
