attached mail follows:


Easy keys seems to be very practical. Oracle is likely to implement this 
feature. Don't take it as a promise though :)

Regarding "easiest keys", the counterintuitive case is valid. However, 
is that a common case? ;)  Do we truly expect
many users define things  like that?

Regarding top/bottom role, I am not totally convinced yet. Could someone 
please describe some practical use cases?
