Merges elements from sequences that are assumed to be sorted by compare to produce a sequence also sorted by compare. If any of the inputs are not sorted, the order of the output is not guaranteed to be sorted.

This includes duplicate elements in the output (whether they occur within one input sequence, or across different input sequences).
