PPI::Statement::Null - A useless null statement

my $foo = 1;

; # <-- Null statement

my $bar = 1;

isa PPI::Statement
    isa PPI::Node
        isa PPI::Element

"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 separator and not a statement 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.

"PPI::Statement::Null" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element.

See the support section in the main module.
