As I understand it, const, immutable, and shared are both type 
qualifiers and storage classes. In C++, const is also both a 
storage class and type qualifier, which causes confusion.

// At global scope
immutable int x = 1;
int y = 2;

Here x and y are stored very differently. y is thread local 
whereas x is a program-wide read-only global. It's a similar 
situation with const and shared.
