NAME

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

SYNOPSIS

   my $foo = 1;
   
   ; # <-- Null statement
   
   my $bar = 1;

INHERITANCE

   PPI::Statement::Null
   isa PPI::Statement
       isa PPI::Node

DESCRIPTION

"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.

METHODS

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

SUPPORT

See the support section in the main module.
