title: Does Perl 6 have an equivalent to Python's update method on dictionary?
body: <p>In Python, if I update the <code>dict</code> dictionary with another dict called <code>u</code>(use <code>Perl</code> as key), it will update the value:</p>
  
  <pre><code>&gt;&gt;&gt; dict = {'Python':'2', 'Perl' : 5}
  &gt;&gt;&gt; u = {'Perl' : 6}
  &gt;&gt;&gt; dict.update(u)
  &gt;&gt;&gt; dict
  {'Python': '2', 'Perl': 6}
  </code></pre>
  
  <p>but in Perl 6 :</p>
  
  <pre><code>&gt; my %hash = 'Python' =&gt; 2, Perl =&gt; 5;
  &gt; my %u = Perl =&gt; 6
  &gt; %hash.append(%u)
  {Perl =&gt; [5 6], Python =&gt; 2}
  </code></pre>
  
  <p>So, Does Perl 6 have an equivalent to Python's update method on dictionary?</p>
