I'm a little uncomfortable with yield as.
We've got:

  import foo as bar
  from foo import zot as bah
  with fred() as bah: ...

All of these place a new name "bah" into the namespace for further use.
"yield as" doesn't, but reads to me like it should.

From the back of the research lab, the sound of a large metallic pile of
loose objects collapsing, accompanied by a loud "Aaaaiiieeyyrrgghhh!!" from
George. A few seconds of silence, then: "I'll have to call you back."
