title: Can vim syntax group be used as a start parameter in syntax match?
body: <p>Suppose I have defined a bunch of <code>syntax keyword</code> and <code>syntax match</code> for some syntax group called <code>Foo</code>.</p>
  
  <p>I would now like to define a <code>syntax region</code> which begins with any match on the syntax group <code>Foo</code> and ends with a literal tab. It would look something like this.</p>
  
  <pre><code>syntax region Bar start=Foo end='\t' 
  </code></pre>
  
  <p><strong>Is this possible?</strong></p>
  
  <p>I have looked at <code>:help :syn-pattern</code> and <code>:help :syn-region</code>, but none of them address this question. This <a href="https://stackoverflow.com/questions/10153078/syntax-region-start-with-a-group">question</a> is kind of similar, but it did not receive good answers (possibly due to lack of sufficient clarity) and is two years old.</p>
