DESCRIPTION
This is a collection of functions for dealing with PPI::Statements.
INTERFACE
Nothing is exported by default.
get_constant_name_elements_from_declaring_statement($statement)
Given a PPI::Statement, if the statement is a Readonly or Const::Fast declaration statement or a "use constant", returns the names of the things being defined.
Given
use constant 1.16 FOO => 'bar';
this will return the PPI::Token::Word containing 'FOO'. Given
use constant 1.16 { FOO => 'bar', 'BAZ' => 'burfle' };
this will return a list of the PPI::Tokens containing 'FOO' and 'BAZ'. Similarly, given
Readonly::Hash my %FOO => ( bar => 'baz' );
or
const my %FOO => ( bar => 'baz' );
this will return the PPI::Token::Symbol containing '%FOO'.
