Yes -- as is expected.  Yield would be much less useful if it only
work with strange restrictions on the structure of the function
containing it.

As far as I can tell, you can pick any function, stick zero or more
yield statements into it, and it will work as expected: hit a yield,
and you get another value for your sequence.
