     * added Binding#source_location.  [Feature #14230]
 
-      This method returns the source location of binding, a 2-element
-      array of __FILE__ and __LINE__.  Traditionally, the same
-      information could be retrieved by <code>eval("[__FILE__, __LINE__]",
-      binding)</code>, but we are planning to change this behavior so that
-      Kernel#eval ignores binding's source location [Bug #4352].
-      So, users should use this newly-introduced method instead of
-      Kernel#eval.
