The IDENTIFIER_NODEs would probably already have been allocated in the 
course of parsing.  Indeed plain strings would probably be better 
datastructures - and the cleanup suggested in the comment above 
is_attribute_p, keeping the lists in canonical form, might make sense too 
- but better to separate such changes into separate patches from the 
minimal patch that changes the datastructure to the form indicated.
