title: How to create spock-style DSL for dataset description?
body: <p>I'd like to have a dataset description in a spock data-driven specs format:</p>
  
  <pre><code>'Key'   |    'Value'    |    'Comments'
  1       |    'foo'      |    'something'
  2       |    'bar'      |    'something else'
  </code></pre>
  
  <p>This has to be transformed to something like 2D array (or whatever is possible to implement).</p>
  
  <p>Any ideas how to implement this data description?</p>
  
  <p>p.s. The biggest problem is linebreak detection, the rest can be implemented by overloading <code>or</code> on Object's <code>metaClass</code>.</p>
