Does the following totally not make sense? I think it should work.

int[] a = new int[10];

a.length += 30;

It's a weird limitation that's been around forever.  Ugh.

Here, have this.

T[] resize(T)(ref T[] arr, ptrdiff_t delta)
{
    arr.length = arr.length + delta;
    return arr;
}

...

auto a = new int[10];
a.resize(30); // now 40
a.resize(-30); // now 10

Unfortunately, the .length property, like all properties, do not support the 'op=' syntax. You have to do it the long way ...

 a.length = a.length + 30;
