The description is not 100% clear to me at the moment. However, empty sequences nested into blocks are now returned. So the issue can be considered resolved.

In the current version (2.3.31), syntax is the following:

def run
  block(:combinator => 'random', :permutator => 'random', :compositor => 'catenation') {
    iterate {
      sequence {
        pseudo 'A1'
        pseudo 'A2'
        pseudo 'A3'
      }
      sequence {}
    }
    iterate {
      sequence {
        pseudo 'B1'
        pseudo 'B2'
        pseudo 'B3'
      }
      sequence {}
    }
    iterate {
      sequence {
        pseudo 'C1'
        pseudo 'C2'
        pseudo 'C3'
      }
      sequence {}
    }
  }.run 10
end

And it gives the following sequences:

//============================================ Test 0 ==============================================

//==================================================================================================
// Test Case 0

//==================================================================================================
// Test Case 1
