New submission from Serhiy Storchaka <[email protected]>:
It would be useful to have a function in itertools to merge sorted iterables.
merge_sorted(*iterables, key=None, reverse=False):
It should emit the same items as sorted(tee(*iterables), key=key,
reverse=reverse) if iterables are sorted with key and reverse. But it should
use the amount of memory O(M) where M is the number of iterables, and support
infinite iterables.
