It's not about the hash table metadata but about speed. Before Ted
rewrote the code, the registry used to do a conversion to/from an alist,
and I remember that writing/reading the registry this way was annoyingly
slow, at least on slow machines in combination with big registries (mine
has about 100.000 entries).
Of course, one could still do that specially for XEmacs. I guess all it
takes is to define a proper ':printer' slot for the registry
object. Someone just has to do it.
