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