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 here.

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.
