=head1 DESCRIPTION
|
|
|
|
C<PPI::Statement::Null> is a utility class designed to handle situations
|
|
where PPI encounters a naked statement separator.
|
|
|
|
Although strictly speaking, the semicolon is a statement B<separator>
|
|
and not a statement B<terminator>, PPI considers a semicolon to be a
|
|
statement terminator under most circumstances.
|
|
|
|
In any case, the null statement has no purpose, and can be safely deleted
|
|
with no ill effect.
|
|
|
|
=head1 METHODS
|
|
|
|
C<PPI::Statement::Null> has no additional methods beyond the default ones
|
|
provided by L<PPI::Statement>, L<PPI::Node> and L<PPI::Element>.
