/// OpenMP 5.0 [2.1.6 Iterators]
/// Iterators are identifiers that expand to multiple values in the clause on
/// which they appear.
/// The syntax of the iterator modifier is as follows:
/// \code
/// iterator(iterators-definition)
/// \endcode
/// where iterators-definition is one of the following:
/// \code
/// iterator-specifier [, iterators-definition ]
/// \endcode
/// where iterator-specifier is one of the following:
/// \code
/// [ iterator-type ] identifier = range-specification
/// \endcode
/// where identifier is a base language identifier.
/// iterator-type is a type name.
/// range-specification is of the form begin:end[:step], where begin and end are
/// expressions for which their types can be converted to iterator-type and step
/// is an integral expression.
/// In an iterator-specifier, if the iterator-type is not specified then the
/// type of that iterator is of int type.
/// The iterator-type must be an integral or pointer type.
/// The iterator-type must not be const qualified.
