| 10 | |||||
| 11 | my $foo = 1; | ||||

| 13 | ; # <-- Null statement | ||||

| 24 | =head1 DESCRIPTION | ||||
| 25 | |||||
| 26 | C<PPI::Statement::Null> is a utility class designed to handle situations | ||||
| 27 | where PPI encounters a naked statement separator. | ||||
| 28 | |||||
| 29 | Although strictly speaking, the semicolon is a statement B<separator> | ||||
| 30 | and not a statement B<terminator>, PPI considers a semicolon to be a | ||||
| 31 | statement terminator under most circumstances. | ||||
| 32 | |||||
| 33 | In any case, the null statement has no purpose, and can be safely deleted | ||||
| 34 | with no ill effect. | ||||
| 35 | |||||
| 36 | =head1 METHODS | ||||
| 37 | |||||
| 38 | C<PPI::Statement::Null> has no additional methods beyond the default ones | ||||
| 39 | provided by L<PPI::Statement>, L<PPI::Node> and L<PPI::Element>. | ||||
