There is some clear low-hanging fruit for Greg's proposal where no trampoline or helpers are needed -- but where currently refactoring complex code containing many yield statements is cumbersome due to the nee to write each "subroutine" call as "for x in subroutine(): yield x" -- being able to replace this with "yield from subroutine()" is a conceptual advantage to me that is not proportional to the number of characters saved.
Right - I don't object to the concept of "yield from" -- I'm -0 on that. What I don't like is the confusion of adding "return values" to generators, at least using the 'return' statement.
