title: Regex for partial match of word?
body: <p>Is it possible to perform the following match?</p>
  
  <p><code>^do something$</code></p>
  
  <p>.. where matches are possible for a partially typed 'something'.</p>
  
  <p>For example:</p>
  
  <pre><code>^do s$
  ^do so$
  ^do som$
  ^do some$
  ^do somet$
  ^do someth$
  ^do somethi$
  ^do somethin$
  ^do something$
  </code></pre>
  
  <p>Is it possible to do this with regex without having to string a bunch of logical ORs?</p>
