I once proposed a similar construct a couple of years ago (it was also
one of my first post in this group)
http://groups.google.com/group/comp.lang.python/browse_thread/thread/ac62e0fe69304c6f/ec95518c16e8b9dc?q

And also, in the last few weeks (or so), there was a thread in
python-ideas mailing list proposing "yieldfrom":

yieldfrom iterable

is equivalent to:

for n in iterable:
    yield n

which is practically the same as what I was and raise-yield is
proposing. The difference being that SoftException/raise-yield silently
re-raise the exception, while yieldfrom is an explicit re-raise.
