Pass closure to builder

[Kerry Wilson]

I need to make a simple DSL that will control permissions.

I would like it to look something like this:

   
role.rules {
  
    // allow access after date
    after('01-01-2009')
    
    // allow access to create articles and reviews
    contentTypes(['article','review'])

    // custom rule allows role to create articles in node 12
    custom {
      
      if( contentType == 'article' && parent == 12 )
          pass()
      else
          fail()
    }
}

Right now the builder is attempting to build the closure, is there any way to make it pass it to the createNode method in my BuilderSupport object or it could execute it and pass the return value.
