As C<$_> is a global variable, this may lead in some cases to unwanted
side-effects. As of perl 5.9.1, you can now use a lexical version of
C<$_> by declaring it in a file or in a block with C<my>. Moreover,
-declaring C<our $> restores the global C<$_> in the current scope.
+declaring C<our $_> restores the global C<$_> in the current scope.
(Mnemonic: underline is understood in certain operations.)
