def ast
  # contracted_clauses.ast will return an array of Clauses, but the first clause is special. We must:
  # * prepend a new role (we get the Role to build *two* ast nodes)
  # * attach the qualifiers
  clauses_ast = contracted_clauses.ast
  clauses_ast[0].conjunction = conjunction.text_value
  clauses_ast[0].phrases.unshift(role.ast)
  clauses_ast[0].certainty = certainty.value

  # A contraction returns an array containing:
  # * a role AST
  # * a qualifiers array
  # * an array of Clauses
  [role.ast, p.empty? ? [] : p.list] + clauses_ast
