Bad things may happen if this module interacts with any other code which
fiddles with package C<0>.
+Performance of creating new deferred or lazy values can be quite poor
+under perl 5.8.9. This is due a bugfix since 5.8.8, where re-blessing
+an overloaded object caused bad interactions with other references to
+the same value. 5.8.9's solution involves walking the arenas to find
+all other references to the same object, which can cause C<bless> (and
+thus L<Scalar::Defer/defer> to be up to three orders of magnitude
+slower than usual. perl 5.10.0 and higher do not suffer from this
+problem.
