I find myself writing a lot of recursive generators, and a while ago I
implemented this:

  yield *other

to mean:

  for x in other:
    yield x

No new keywords, and the asterisk is already used for a similar
purpose (iterator expansion) in the function call syntax.

Thoughts? "Neat!" or "Yuck!"?
