Ticket #606 (closed roadmap: invalid)
prune c data structures
|Reported by:||allison||Owned by:||chromatic|
Some C data structures in Parrot core contain members that are no longer used. Review them, and remove unneeded entries.
(Note that to make these changes in 2.0, they will need deprecation notices in the 1.4 release, so the review needs to happen at least 6 months before 2.0.)
