Yes. const = you can't change. Changing it is invalid behavior.
Imagine const/immutable as bits in readonly memory and you'll
have to right mindset.
What would you do, if you need in a special case a mutable
version or must change the object itself?
Because there is no "mutable" keyword in D you have to cast
away the constness.
In what way do you mean? If it's something you honestly _need_
to change and it's const, then maybe throwing an exception
would be appropriate.
I thought that const = "cannot change directly" and immutable
stands for "cannot change all the time". If not, why exist both
storage classes beside?
