/* Type PyByteArrayObject represents a mutable array of bytes.

 * The Python API is that of a sequence;

 * the bytes are mapped to ints in [0, 256).

 * Bytes are not characters; they may be used to encode characters.

 * The only way to go between bytes and str/unicode is via encoding

 * and decoding.

 * For the convenience of C programmers, the bytes type is considered

 * to contain a char pointer, not an unsigned char pointer.
