Splitter returns a forward range so you can't slice the result. 
You can use take() and drop() instead. Also, converting a string 
range to int[] doesn't seem to work, but I don't know if it 
should. Here is a version that works:

```D
import std;

void main() {
     struct DateRem {
         Date date;
         string rem;
         string toString() const => text(date.toSimpleString, " ", 
rem);
     }
     DateRem[] daterem;
     data
         .splitter('\n')
         .filter!(l => l.length && l[0].isDigit)
         .each!((l) {
             auto parts=l
                    	.splitter
                 	.take(3)
                 	.map!(to!int)
                 	.array;
             if (parts.length==3) {
                 daterem~=DateRem(Date(parts[2],parts[1],parts[0]),
                             l.splitter.drop(3).join(" "));
	        }
         });
	daterem.each!writeln;
}

auto data="04 10 2023 17:28, not much
30 9 2023 21:08, very little";
```
