use constant
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' );
this will return the PPI::Token::Symbol containing '%FOO'.
