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)));
}
