/**
 * Repeats each element of the stream using the provided schedule. When the schedule is finished,
 * then the output of the schedule will be emitted into the stream. Repetitions are done in
 * addition to the first execution, which means using `Schedule.recurs(1)` actually results in
 * the original effect, plus an additional recurrence, for a total of two repetitions of each
 * value in the stream.
 *
 * This function accepts two conversion functions, which allow the output of this stream and the
 * output of the provided schedule to be unified into a single type. For example, `Either` or
 * similar data type.
