WebbI think this one's my favourite -- make a [ [u8; 4]; 2], which autorefs to & [ [u8; 2], and the method turns into & [u8], which you then ask for as a [u8; 8], which it always is, so the checking optimizes away. And it compiles perfectly -- same as the copy_from_slice version (or the manual shifting below).
