- !ruby/struct:SM::Flow::P 
  body: A <tt>Hash</tt> is a collection of key-value pairs. It is similar to an <tt>Array</tt>, except that indexing is done via arbitrary keys of any object type, not an integer index. The order in which you traverse a hash by either key or value may seem arbitrary, and will generally not be in the insertion order.
- !ruby/struct:SM::Flow::P 
  body: Hashes have a <em>default value</em> that is returned when accessing keys that do not exist in the hash. By default, that value is <tt>nil</tt>.
- !ruby/struct:SM::Flow::P 
  body: <tt>Hash</tt> uses <tt>key.eql?</tt> to test keys for equality. If you need to use instances of your own classes as keys in a <tt>Hash</tt>, it is recommended that you define both the <tt>eql?</tt> and <tt>hash</tt> methods. The <tt>hash</tt> method must have the property that <tt>a.eql?(b)</tt> implies <tt>a.hash == b.hash</tt>.
