+- Generators were added; this is a new way to create an iterator (see
+ below) using what looks like a simple function containing one of
+ more 'yield' statements. See PEP 255. Since this adds a new
+ keyword to the language, this feature must be enabled by including a
+ future statement: "from __future__ import generators" (see PEP 236).
+ Generators will become a standard feature in a future release
+ (probably 2.3). Without this future statement, 'yield' remains an
+ ordinary identifier, but a warning is issued each time it is used.

+ PEP 230; we intend to fix this in 2.2a2.)
