What you proposed sounds like it would be cleaner and less work than
further perverting the index system as a source of information about
types or hard-coding knowledge anywhere else.

Not really. Unless I've missed something domains are a single-level
layer over a data type. I find them very useful and use them
heavily, but the standard implementation is rather limited. Perhaps
that would be the area to add the functionality I suggested, though.
I'm totally at the hand-waving stage on it, with no concrete ideas.
I just thought that if you were adding more type information,
oriented aournd the types themselves rather than index AMs, some form
of inheritence might fit in gracefully.
