I think that yield is part of the general concept of coroutines and has
not really been invented by Python nor C# (Knuth if I remember
correctly). Then again, I did not really read anything about the C#
yield, so I'm not sure it is really about coroutines (btw, why the
"yield return" syntax and not just "yield"?).

Speaking of more Boost centric stuff? There has been any proposal of a
coroutine library? I think it should definitely be useful and not really
that hard to implement (fibers on windows and makecontext or the
setjump/sigaltstack trick on unices). Anyone interested?
