135 .IX Header "SYNOPSIS"
137 \& # All of the following are variable declarations
139 \& my ($foo, $bar) = (1, 2);
143 \& LABEL: my $foo = 1;

155 .IX Header "DESCRIPTION"
156 The main intent of the \f(CW\*(C`PPI::Statement::Variable\*(C'\fR class is to describe
157 simple statements that explicitly declare new local or global variables.
159 Note that this does not make it exclusively the only place where variables
160 are defined, and later on you should expect that the \f(CW\*(C`variables\*(C'\fR method
161 will migrate deeper down the tree to either PPI::Statement or
162 PPI::Node to recognise this fact, but for now it stays here.
166 .IX Subsection "type"
167 The \f(CW\*(C`type\*(C'\fR method checks and returns the declaration type of the statement,
168 which will be one of 'my', 'local', 'our', or 'state'.
170 Returns a string of the type, or \f(CW\*(C`undef\*(C'\fR if the type cannot be detected
171 (which is probably a bug).
173 .IX Subsection "variables"
174 As for several other \s-1PDOM\s0 Element types that can declare variables, the
175 \&\f(CW\*(C`variables\*(C'\fR method returns a list of the canonical forms of the variables
176 defined by the statement.
178 Returns a list of the canonical string forms of variables, or the null list
179 if it is unable to find any variables.
181 .IX Subsection "symbols"
182 Returns a list of the variables defined by the statement, as
