title: Regex to match a word with at least one letter and any number of digits (no lookaround)
body: <p>I'm new to regular expressions and I'm trying to come up with a regex which matches a word which contains at least one letter and zero or more digits.</p>
  
  <p>Example:</p>
  
  <p><code>users</code> - match</p>
  
  <p><code>u343sers</code> - match</p>
  
  <p><code>13123123</code> - not match</p>
  
  <p>I cannot use lookarounds because I need to use the regex in Go and the <code>regexp</code> package doesn't support them.</p>
  
  <p>Is this possible without lookarounds?</p>
