title: How to concat two (IO) Strings in Haskell?
body: <p>I know this sound very simple, but I failed to combine two strings into a new one.</p>
  
  <p>The IO String "a" from a gtk entry is fetched by</p>
  
  <pre><code>      a &lt;- (entryGetText text_field)
  </code></pre>
  
  <p>The goal is to combine it like:</p>
  
  <p>newstring = "Text: "+a</p>
  
  <p>Any ideas to accomplish that?
  Thanks!</p>
