   1 * Things to think about
   2
   3   + Reorganize output protocol so that metaclasses can override the
   4     layout.  Split ~hook-output~ into a pair of generic functions: one
   5     for walking the tree, which should continue to be
   6     ~progn~-combination, and one for producing output, which subclasses
   7     can override.
   8
   9   + Investigate a `robust-ABI' layout using pointers rather than simple
  10     inclusion.  Each class's islots and vtmsgs will be found by
  11     following a pointer rather than just magically knowing the offsets.
  12     If you allocate objects dynamically, using ~CLASS->cls.initsz~
  13     rather than ~sizeof(CLASS__ilayout)~ then this isolates you from
  14     added slots and messages at all superclasses.  I expect this to
  15     require a separate root class, but it /might/ be possible to
  16     mix-and-match.
