Recent reported regression issue 9539 has been caused by the deprecated implicit conversion T[] to T*.
I think it's a good time to remove such conversions, both T[n] to T* and T[] to T*, completely (I think it is necessary for the regression fix).
See https://github.com/D-Programming-Language/dmd/pull/1679 and related [my bugzilla comment](http://d.puremagic.com/issues/show_bug.cgi?id=9539#c1).
