Thanks to you and the others for the detailed clarifications. I 
think part of the difficulty is that there are basically three 
things being discussed that are all very similar: an alias to 
data, a pointer to data, and a view of data.


so, what that quote essentially means is: "`const` pointers can 
point to mutable data, but `immutable` pointers cannot".


So an immutable pointer guarantees that whatever it is pointing 
to will never change, but a const pointer can also point to 
mutable data, which might change some other way.
