Access modifiers

The released compiler supports public and private members.

Modifier	Visibility
public	Visible everywhere in the compilation
private	Restricted to the declaring class

public class Account {
    private int balance;
    public bool isActive;

    public Account(int initial) {
        this.balance = initial;
        this.isActive = true;
    }

    public int GetBalance() { return this.balance; }
}

protected is not useful in the current release because inheritance is not yet supported. Static methods are supported; static fields are not.
