+Relation between overloading and tie()ing is broken. Overloading is
+triggered or not basing on the I<previous> class of tie()d value.
+
+This happens because the presence of overloading is checked too early,
+before any tie()d access is attempted. If the FETCH()ed class of the
+tie()d value does not change, a simple workaround is to access the value
+immediately after tie()ing, so that after this call the I<previous> class
+coincides with the current one.
+
+B<Needed:> a way to fix this without a speed penalty.
