You're not using correct syntax.  The first problem line, auto  numbers3 = [ 1, 2, 3, 4][];, doesn't work because you forgot a comma.  I think you want auto to be evaluated as int[][], however, you have two arrays without a comma seperator.  It should be like this:

auto numbers3 = [ 1, 2, 3, 4], [];

The second line has the same problem, as well as it's improperly declared.  It should be declared as int[][].
