Both cannot change, but one is typed as const and the other as 
immutable. You usually don't want to declare const variables that way, 
because they cannot be passed by reference to immutable even though 
technically they would be immutable.

more sense to be always placed in mutable memory, so that they could
be used as logical consts.
