I assumed it would generate separate integers 123 and 456. I started to implement a range with findSkip, findSplit, and friends but failed. :/

It's called hit two targets with one arrow:

```d
auto splitNumbers(string str)
{
  size_t[] n = [0];
  size_t i;
  foreach(s; str)
  {
    if(s >= '0' && s <= '9')
    {
      n[i] = 10 * n[i] + (s - '0');
    } else {
      i++;
      n.length++;
    }
  }
  return n.filter!(c => c > 0);
}

void main()
{
  auto s = "abc1234567890def1234567890xyz";
  s.splitNumbers.writeln; // [1234567890, 1234567890]
}
```
