Then, the following points must be decided to define the complete list of supported features (formatters):

* Format integer to hexadecimal? %x and %X * Format integer to octal? %o * Format integer to binary? {!b} * Alignment? * Truncating? Truncate or raise an error? Not desirable IMHO. bytes formatting should serve mainly for templating situations (i.e. catenate and insert bytestrings into one another). We cannot start giving text-like semantics to bytes objects without confusing non-experts.

But having at least some of struct's formatting options available on bytes.format or bytes % would be useful.
