  * A random-access sequence of bytes that also provides random access to
  * the fixed-width integers and floating point numbers represented by
  * those bytes. Byte arrays may be used to pack and unpack data from
  * external sources (such as networks or files systems), and to process
  * large quantities of numerical data more efficiently than would be possible
  * with ordinary [List] implementations. Byte arrays can save space, by
  * eliminating the need for object headers, and time, by eliminating the
  * need for data copies. Finally, Byte arrays may be used to intentionally
  * reinterpret the bytes representing one arithmetic type as another.
