    <![CDATA[
    Using the logical "and" and "or" operators is not allowed.

    The logical "and" and "or" operators have a significantly lower operator precedence than their boolean "&&" and "||" counter-parts, which often leads to unexpected bugs.
    The boolean "&&" and "||" operators are nearly always the better choice.
