=head1 NAME
PPI::Statement::Null - A useless null statement
=head1 SYNOPSIS
my $foo = 1;
; # <-- Null statement
my $bar = 1;
=head1 INHERITANCE
PPI::Statement::Null
isa PPI::Statement
isa PPI::Node
isa PPI::Element
=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>.
