ref Element opIndexAssign( in Element a, in uint n ) { data[n] += a; return data[n]; }I'm guessing as I don't use 2.0 but I think that this is a bug. DMD is trying to say that the above returns are trying to return something that can't be referenced (like a math expression result).It is a bug, indeed. The struct 'invariant' prevents proper template instantiation somehow... Removing it makes code work as intended.I'll submit a bug report.
Thank you! Give a link to the bugreport later?
