Isn't the 'override' keyword required? (Perhaps required only in D2?)

I find string.format very helpful in toString() member functions.

Finally, I still don't know whether the 'const'ness of the member 
function is required, allowed, or completely wrong. :)

import std.string;

class A
{
    override string toString() const
    {
        return format("My %s formatted string: %s", "lovely", 42);
    }
}
