I have this code

template Point()
{
 real x,y;
}

class FourPoints
{
 mixin Point T1;
 mixin Point T2;
 mixin Point T3;
 mixin Point T4;
}

And inside this class i can use T1.x, T2.y!

but in main i have:

FourPoints FP = new FourPoints();
FP.T1.x = 3;

but this last line causes:
E:\D language\opengl\ifs\ifs.d(185): FP.Point!() T1 is not a declaration
Obviously i can't use FP.x = 3; beacause then i get:
E:\D language\opengl\ifs\ifs.d(28): variable x conflicts with Point!() T2.x
at E:\D language\opengl\ifs\ifs.d(28)

Hope this is a bug :) and not a feature.

Yes, it's a bug.
