Then let me explain it.  We've had a few months since 2.2, and that
was a release with so many new things (and bugs) that many of the more
conservative users probably steered clear of it.  It'll be another
half year until 2.3 can fix this feature.  But until then (or really,
until 2.3.1 is out!), more people will probably use 2.2.1 than have
already used it.  So since it's *possible* that someone will find a
use for PyCell_GET(), I'd prefer them to have access to the fixed
version.
