	Module Stream defines an interface for external iterators. A stream can be seen as an iterator on a sequence of objects x1, ..., xn. The state of the stream is uniquely determined by the following methods: at_beginning?, at_end?, current, and peek. State changes are done with the following operations: set_to_begin, set_to_end, forward, and backward.
