  Add *,**,@ to index, as suggested by
  http://farmdev.com/thoughts/24/what-does-the-def-star-variable-or-def-asterisk-parameter-syntax-do-in-python-/

  The right entry type to use isn't clear; operator seems wrong, because *,**,@
  aren't being used in expressions here.  I put them as 'statement'; 'syntax'
  might be better.
