[Q] is 'yield from' syntax sugar for 'for'+'yield'?

[Makoto Kuwata]

Question about 'yield from'.

I understand that::

    yield from xs

is syntax suger of::

    for x in xs:
      yield x

And::

    val = yield from xs

is same as::

    for x in xs:
      ret = yield x
    val = ret

Is it true? Do I understand correctly?
