Well, if you're programming in a C-style fashion, where you just have a 
bunch of global data and a bunch of functions to manipulate it.. I suppose 
it's kind of _messy_ and certainly not my preferred method, but there's 
nothing stopping _you_ from doing it :)

One of the problems of using a large global array is that it's allocated in 
the static data segment.  This isn't a problem if you just define

int[500][500] x;

But if you initialize any of it statically:

int[500][500] x = [0 : [0 : 1]];

(which means set x[0][0] = 1)

It makes the EXE size jump up quite a bit.  In this case, by about 1MB.

You can get around this by using static module constructors though:

int[500][500] x;

static this()
{
    x[0][0] = 1;
}
