If you don't quite understand what you're looking at (output of deparse, perl syntax), then ppi_dumper can help you look at the right part of the manual, an example

$ ppi_dumper 2
PPI::Document
  PPI::Statement::Include
    PPI::Token::Word    'use'
    PPI::Token::Whitespace      ' '
    PPI::Token::Word    'constant'
    PPI::Token::Whitespace      ' '
    PPI::Token::Word    'X'
    PPI::Token::Whitespace      ' '
    PPI::Token::Operator        '=>'
    PPI::Token::Whitespace      ' '
    PPI::Token::Number          '1'
    PPI::Token::Operator        '/'
    PPI::Token::Number          '3'
    PPI::Token::Structure       ';'
  PPI::Token::Whitespace        '\n'
  PPI::Token::Whitespace        '\n'

So PPI::Token::Operator tells you "=>" is an operator

If you read perl/"perltoc" then you'll know that operators are documented in perlop
