How to const-overload opEquals(R)(R rhs)?

[Tobias Pankrath]

Hey,

let's say I have a simple struct and I want to give it an 
opEquals like this.

struct Point
{
    int x, y;
    bool opEquals(R)(R rhs) { return x == rhs.x && y == rhs.y; }
}


With this I can't call opEquals on const instances of Point, 
because dmd says

bug.d(13): Error: function bug.Point.opEquals!(Point).opEquals 
(Point rhs) is not callable using argument types (Point) const

So I overoad is with a const version of oqEquals:

struct Point
{
    int x, y;
    bool opEquals(R)(R rhs) { return x == rhs.x && y == rhs.y; }
    bool opEquals(R)(R rhs) const { return x == rhs.x && y == 
rhs.y; }
}

But the error stays the same. So why is the const version not 
taken into consideration?

Thanks for your answers.
