 Both string and bytes literals may optionally be prefixed with a letter ``'r'``

 PEP 3151: Reworking the OS and IO exception hierarchy
@@ -261,9 +262,56 @@ part of its operations to another generator. This allows a section of code
 containing 'yield' to be factored out and placed in another generator.
 Additionally, the subgenerator is allowed to return with a value, and the
 value is made available to the delegating generator.
+
 While designed primarily for use in delegating to a subgenerator, the ``yield
 from`` expression actually allows delegation to arbitrary subiterators.
 
+For simple iterators, ``yield from iterable`` is essentially just a shortened
+form of ``for item in iterable: yield item``::
+
+    >>> def g(x):
+    ...     yield from range(x, 0, -1)
+    ...     yield from range(x)
+    ...
+    >>> list(g(5))
+    [5, 4, 3, 2, 1, 0, 1, 2, 3, 4]
+
+However, unlike an ordinary loop, ``yield from`` allows subgenerators to
+receive sent and thrown values directly from the calling scope, and
+return a final value to the outer generator::
+
+    >>> def accumulate(start=0):
+    ...     tally = start
+    ...     while 1:
+    ...         next = yield
+    ...         if next is None:
+    ...             return tally
+    ...         tally += next
+    ...
+    >>> def gather_tallies(tallies, start=0):
+    ...     while 1:
+    ...         tally = yield from accumulate()
+    ...         tallies.append(tally)
+    ...
+    >>> tallies = []
+    >>> acc = gather_tallies(tallies)
+    >>> next(acc) # Ensure the accumulator is ready to accept values
+    >>> for i in range(10):
+    ...     acc.send(i)
+    ...
+    >>> acc.send(None) # Finish the first tally
+    >>> for i in range(5):
+    ...     acc.send(i)
+    ...
+    >>> acc.send(None) # Finish the second tally
+    >>> tallies
+    [45, 10]
+
+The main principle driving this change is to allow even generators that are
+designed to be used with the ``send`` and ``throw`` methods to be split into
+multiple subgenerators as easily as a single large function can be split into
+multiple subfunctions.

+To ease the transition from Python 2 for Unicode aware Python applications

+in Python 3, it is provided solely to reduce the number of purely mechanical

-# From SF bug #422121:  Insecurities in dict comparison.
-
-# Safety of code doing comparisons has been an historical Python weak spot.
-# The problem is that comparison of structures written in C *naturally*
-# wants to hold on to things like the size of the container, or "the
-# biggest" containee so far, across a traversal of the container; but
-# code to do containee comparisons can call back into Python and mutate
-# the container in arbitrary ways while the C loop is in midstream.  If the
-# C code isn't extremely paranoid about digging things out of memory on
-# each trip, and artificially boosting refcounts for the duration, anything
-# from infinite loops to OS crashes can result (yes, I use Windows <wink>).
-#
-# The other problem is that code designed to provoke a weakness is usually
-# white-box code, and so catches only the particular vulnerabilities the
-# author knew to protect against.  For example, Python's list.sort() code
-# went thru many iterations as one "new" vulnerability after another was
-# discovered.
-#
-# So the dict comparison test here uses a black-box approach instead,
-# generating dicts of various sizes at random, and performing random
-# mutations on them at random times.  This proved very effective,
-# triggering at least six distinct failure modes the first 20 times I
-# ran it.  Indeed, at the start, the driver never got beyond 6 iterations
-# before the test died.
-
-# The dicts are global to make it easy to mutate tham from within functions.
