This was an interesting read. It would be nice to see a discussion
of how const is going to fit in in terms of optimization potential,
since you can always cast it away.
It's basically useless for optimizations I think. Even if the view of
the data you have is const, someone else might have a non-const view
of the same data. So for instance, if you call any function, your
"const" data could have been changed via non-const global pointers to
the same data.
Right. It's useless.
Casting away const and immutable also puts one into undefined behavior
territory.
