-- | Class Hashable providing a hash method.
--   
--   This package provides a class <a>Hashable</a>, which contains one
--   method <tt><a>hash</a> :: <a>Hashable</a> a =&gt; a -&gt;
--   <a>Int</a></tt>, which returns the hash of the given element.
--   
--   The instances for various integral types, <a>String</a> and
--   <a>ByteString</a> are provided.
@package hashable
@version 1.0.0


-- | <a>Hashable</a> class for hashable types, with instances for basic
--   types. The only function of this class is
--   
--   <pre>
--   <a>hash</a> :: Hashable h =&gt; h -&gt; Int
--   </pre>
--   
--   The <a>hash</a> function should be as collision-free as possible, the
--   probability of <tt><a>hash</a> a == <a>hash</a> b</tt> should ideally
--   be 1 over the number of representable values in an <a>Int</a>.
--   
--   Returning an <a>Int</a> is a result of the <tt>Data.IntMap.IntMap</tt>
--   using <a>Int</a> as a key, as inserting the hash values to the
--   <tt>Data.IntMap.IntMap</tt> was the purpose of creating this class.

-- | The class containing a function <a>hash</a> which computes the hash
