		Instances for Binary for the types defined in the vector package,
		making it easy to serialize vectors to and from disk. We use the
		generic interface to vectors, so all vector types are supported.
		Specific instances are provided for unboxed, boxed and storable
		vectors.
		
		To serialize a vector:
		
		&gt; *Data.Vector.Binary&gt; let v = Data.Vector.fromList [1..10]
		&gt; *Data.Vector.Binary&gt; v
		&gt; fromList [1,2,3,4,5,6,7,8,9,10] :: Data.Vector.Vector
		&gt; *Data.Vector.Binary&gt; encode v
		&gt; Chunk "\NUL\NUL\NUL\NUL\NUL...\NUL\NUL\NUL\t\NUL\NUL\NUL\NUL\n" Empty
		
		Which you can in turn compress before writing to disk:
		
		&gt; compress . encode $ v
		&gt; Chunk "\US\139\b\NUL\NUL\N...\229\240,\254:\NUL\NUL\NUL" Empty
