OK I answered my own question...sorry. But here is the answer in case
someone else asks the same silly question:

Use a string as a key (doh!)

@documentnames = {
   'finance_whitepaper' => 'whitepaper one',
   'ecommerce_whitepaper' => 'whitepaper two',
   'integratedsvs_datasheet' => 'whitepaper three'
  }

Problem solved!
