These checks can be disabled via pragmas or invoking the compiler with the ``--boundChecks:off`` command line switch. -The current implementation does not support nested open arrays. + +Open arrays +----------- + +Often fixed size arrays turn out to be too inflexible; procedures should +be able to deal with arrays of different sizes. The `openarray`:idx: type +allows this; it can only be used for parameters. Openarrays are always +indexed with an ``int`` starting at position 0. The ``len``, ``low`` +and ``high`` operations are available for open arrays too. Any array with +a compatible base type can be passed to an openarray parameter, the index +type does not matter. In addition to arrays sequences can also be passed +to an open array parameter. + +The openarray type cannot be nested: multidimensional openarrays are not +supported because this is seldom needed and cannot be done efficiently.
