SYNOPSIS
	   use PPI::Document qw< >;

	   use PPIx::Utilities::Statement qw<
	       get_constant_name_elements_from_declaring_statement
	   >;

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

	   # Returns the PPI::Token::Symbol for "$THINGY".

	   );

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'.
