In my unittest I tried to test out my rotate function. assert(Vec2(1,2).rotate(90) == Vec(-2,1)); But I got these compile errors: vector.d(156): Error: function vector.Vec.opEquals (Vec) does not match parameter types (void) vector.d(156): Error: cannot implicitly convert expression (opCall(1,2).rotate(opCall(90))) of type void to Vec*
2 questions: My opEquals takes an Vec2 and not a *Vec2, is this wrong? Why is return value of the rotate function compared and not the rotated struct literal?
