title: Convert AST nodes string to groovy code
body: <p>I want to create groovy code using AstBuilder, but afterwards, I'd like to see how the actual groovy code would look like.
  Is it possible to convert AST nodes' toString output like this:</p>
  
  <pre><code>org.codehaus.groovy.ast.stmt.BlockStatement@5b7a5baa[
  org.codehaus.groovy.ast.stmt.ExpressionStatement@776aec5c[
  expression:org.codehaus.groovy.ast.expr.DeclarationExpression@1d296da[
  org.codehaus.groovy.ast.expr.VariableExpression@7c7a06ec[
  variable: cl]("=" at 2:17:  "=" )org.codehaus.groovy.ast.expr.ClosureExpression@13c9d689[
  ]{ org.codehaus.groovy.ast.stmt.BlockStatement@75d4a5c2[
  ] }]]]
  </code></pre>
  
  <p>back into groovy code?</p>
