I've got a lot of code with two-dimensional arrays, where I use 
stuff like:

 assert(matrix.all!(a=>a.all!(b=>b>=0)));

Does anyone know if there is a 2D-version of all so I can write 
something like:

 assert(matrix.all2D!(a=>a>=0));

auto all2d(alias f)(ref Matrix m)
{
      return m.all!(a => a.all!(b => f(b)));
