Playing with 'yield from'.

    from itertools import count

    def foo():
        yield from range(3)
        yield from ('hello', 'world')
        yield from count()

    list(x[0] for x in zip(foo(), range(10)))

    # See PEP 380 https://www.python.org/dev/peps/pep-0380/

By the way, that last line's way of limiting a generator to n values
looks ugly. What's a Pythonic way of doing that?

Premature optimization is the root of all evil.

For the love of money is the root of all evil:
which while some coveted after,
they have erred from the faith,
and pierced themselves through with many sorrows.
