+=head1 BUGS
+
+As of Perl 5.8.0 after using this module you cannot use the implicit
+C<$_> or the special filehandle C<_> with stat() or lstat(), trying
+to do so leads into strange errors.  The workaround is for C<$_> to
+be explicit
+
+    my $stat_obj = stat $_;
+
+and for C<_> to explicitly populate the object using the unexported
+and undocumented populate() function with CORE::stat():
+
+    my $stat_obj = File::stat::populate(CORE::stat(_));

+While this class is currently implemented using the Class::Struct
 module to build a struct-like class, you shouldn't rely upon this.
