       PPI::Statement::Variable - Variable declaration statements

	 # All of the following are variable declarations
	 my $foo = 1;
	 my ($foo, $bar) = (1, 2);
	 our $foo = 1;
	 local $foo;
	 local $foo = 1;
	 LABEL: my $foo = 1;

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

       The main intent of the "PPI::Statement::Variable" class is to describe simple statements
       that explicitly declare new local or global variables.

       Note that this does not make it exclusively the only place where variables are defined,
       and later on you should expect that the "variables" method will migrate deeper down the
       tree to either PPI::Statement or PPI::Node to recognise this fact, but for now it stays

       The "type" method checks and returns the declaration type of the statement, which will be
       one of 'my', 'local', 'our', or 'state'.

       Returns a string of the type, or "undef" if the type cannot be detected (which is probably
       a bug).

       As for several other PDOM Element types that can declare variables, the "variables" method
       returns a list of the canonical forms of the variables defined by the statement.

       Returns a list of the canonical string forms of variables, or the null list if it is
       unable to find any variables.

       Returns a list of the variables defined by the statement, as PPI::Token::Symbols.
