+=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>.
