Disclaimer the second DIP is mine.
The first is mostly concerned with syntax sugar.
The second is about modelling externally setting internal (but private)
attributes that are visible publicly.
They both have their own pluses and minuses, but IMO the second is much
harder to implement as a library. In fact we already do, see ElementType
for input ranges. We can do better at modelling this.
