OK, so I've been thinking about this some more, and here's a possible 
alternate proposal for IndexGetter/IndexSetter.   The Name situation is 
harder, unfortunately....

Proposal:  Trying to create an indexed property outside the range 
supported by the IndexSetter throws.  If there is an IndexGetter but no 
IndexSetter, the relevant range is empty.

This has an obvious drawback: throwing in situations where UAs currently 
do not.  Said UAs don't interoperate very well on such cases, though 
so it might be that the compat impact is low.

Obvious benefit: not having to define how user-defined properties have 
to interact with IndexGetter/Setter stuff, since there is no interaction 
between the two anymore.

This is pretty off-the-cuff; are there obvious things that would go 
wrong in this setup?

And as I said, not a good option for NameGetter/Setter....
