So the behavior of bool in this case is consistent with the 
behavior of other integral types.


We all understand that, but in that case, it's the programmer's 
fault (or intention!) for giving different behavior between the 
two.

In the bool/long case, the programmer is writing perfectly 
logical code, and it's the compiler that interprets it a weird 
way.

You can see the difference more clearly here:

        void print(long a, bool newline = false)
        {
            write(a);
            if (newline)
                writeln();
        }

        void print(bool newline = false)
        {
            if (newline)
                writeln();
        }
        
        void main()
        {
            print(1);
            print(2);
        }


Are you really going to blame the programmer for expecting this 
to print

        1
        2

or are you going to blame the language for not doing so?
