UnboundLocalError is in the CVS development tree, but is not in 1.5.2.

Tom noted the dangers of separating the doc release from the code release,
so he'll be pleased to see the point has been illustrated <wink>.  I'll add
that there's also a downside to the public CVS tree:  many of us corporate
apologists don't run the released 1.5.2 anymore, so say stuff that isn't yet
true for those who are.  Perl's corporate apologists have been doing this
for years, though <wink>.
