    :   that causes a shell to give cryptic error messages.
  • To point out and clarify typical intermediate level semantic
    :   problems, that causes a shell to behave strangely and
    :   counter-intuitively.

    :   cause an advanced user’s otherwise working script to fail under
    :   future circumstances.
