That would be good, in my opinion. I updated PEP 3XX to use this idea: http://members.iinet.net.au/~ncoghlan/public/pep-3XX.html With that update (to version 1.6), PEP 3XX is basically PEP 343, but injecting exceptions that occur into the template generator's internal frame instead of invoking next(). The rest of the PEP is then about dealing with the implications of allowing yield inside try/finally statements. The Rejected Options section tries to look at all the alternatives brought up in the various PEP 310, 340 and 343 discussions, and explain why PEP 3XX chooses the way it does.
