so the new syntax would not be useful, unless it was something that provided access to the index item as a variable, like:

yield foo(i) for i in x which barely saves you anything (a colon, a newline, and an indent).

Not even that, because you can omit the newline and indent:

for i in x: yield foo(i)

There's a bigger difference between

for i in x: yield i

and

yield from x

Moreover, I can imagine optimization opportunities for "yield from" that would not make sense in the context of comprehensions.
