New submission from pyos:
Since "yield from" made it into Python 3.3, I think it would be useful to chain
multiple generators and still get a generator, not an iterator. That is, the
following code:
def f():
yield from itertools.chain(A, B, C)
should be (at least roughly) equivalent to
def f():
yield from A
yield from B
yield from C
while still allowing to send() values to whichever subgenerator is currently
running or throw() exceptions inside them.
The attached patch adds this functionality to itertools.chain objects.
