    Append a result to its internal chain of results. It has a special behavior for SET commands as SET is discarded if there are other results in the chain. If this is a SET command, the newResult is returned has the new head of the chain. If the newResult is a SET command, it's not appended and this is returned.
    
    Parameters:
    
    newResult - the result to append
    
    Returns:
    
    the head of the chain
