Woah! I thought I had said:

I'm well aware of the scope rules for IFF. It's perfectly all right
to define a hunk type with the same name as something else, but different
contents, so long as it appears in the correct context (namely, a DR2D
FORM). However, since his CMAP hunk is functionally identical to an ILBM
CMAP, it just seemed wasteful (and possibly confusing to new IFF programmers)
to define a whole new one, and write new code for it.
But of course, he's perfectly free to do whatever he feels is right.
