  Scenario: Keeping used expression 1
    When executing query:
      """
      MATCH (n)
      RETURN cOuNt( * )
      """
    Then the result should be:

      | 1          |
    And no side effects

  Scenario: Keeping used expression 2
    When executing query:

    Then the result should be:

    And no side effects

  Scenario: Keeping used expression 3
    When executing query:
      """
      MATCH p = (n)-->(b)

  Scenario: Keeping used expression 4
