as a reminder, the old conversion was that you could write var arr [10]byte; var slice []byte; slice = arr; but now you have to write slice = &arr; the change eliminates an implicit &, so that the only implicit &s left are in the . operator and in string(arr). also, removed utf8.EncodeRuneToString in favor of string(rune).
