public interface ArrayMode

Interface for those functions that evaluate arguments in array mode depending on context.

When an operator (e.g. = or *) has an area operand and its result is an argument of such a function, the operator is evaluated element-wise over the area instead of being reduced to the single value for the formula's cell. Both Functions and FreeRefFunctions (user-defined and "future" functions such as XLOOKUP) may implement this marker.
