I believe he was referring indirectly to 
http://www.python.org/peps/pep-0342.html (see item #1 in the 
"Specification Summary" section), where yield will become an expression. 
  This PEP has been accepted, thus his use of present tense, confusing 
though it is when it's not in the released version of Python yet.

Or I might be wrong. ;-)
