Array as function argument

When I've callback defined as

``` c
#define COUNT 10
void (*cl)(int list[COUNT]);
```

swig produces

``` xml
<attribute name="decl" value="f(a(COUNT).int)." id="19616" addr="0xbf61b8" />
```

and it appears

``` ruby
callback([ a(COUNT).int ], :void)
```

but it probably should be

``` ruby
callback([ [:int, 10] ], :void)
```

only that's not supported yet, see ffi/ffi#385
