+0.00400    Oct 28, 2008
+           - Fix bug where a bad assumption was causing us to infinitely loop
+             on badly-written code like Data::Page. (Reported by marcus)
+             - Tests for this
+             - Up Moose dep to 0.31 
 0.00300    Jul XX, 2008
            - Replace around 'new' with a BUILD method. Faster and avoids Moose
              bug with around/immutable and sub-classes.
