>;
my $document = PPI::Document->new(\'Readonly::Scalar my $THINGY => 47.2;');

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'.
