I have updated my prototype yield-from implementation to work with Python 3.1.2.

My work is primarily on the management and analysis of huge genomics datasets. I use Python generators extensively and intensively to perform efficient computations and transformations on these datasets that avoid the need to materialize them in main memory to the extent possible. I've spent a great deal of effort working around the lack of an efficient "yield from" construct and would be very excited to see this feature added. More so, now that BioPython, NumPy, SciPy and other libraries that I depend on are well on their way to supporting Python 3, the availability of this feature alone would be incentive enough to update my code base to Python 3. So in short: +1 -Kevin
