I was thinking that a class can define an arbitrary toString() 
that modifies it some of its member variables, which definitely 
breaks const-correctness.

class CustomToString
{
    int n;

    override string toString()
    {
        n = 1;

        return "Uh oh";
    }
}

void main()
{
    import std.stdio;

    immutable c = new CustomToString();
    writeln(cast()c);
}
