Slightly modified version from the Tango manual:

import tango.core.Array;
import tango.text.Ascii;
import tango.io.Console;

void main()
{
    char[][] n;

    n ~= "1";
    n ~= "10";
    n ~= "2";
    n ~= "24";

    n.sort( ( char[] l, char[] r ) { return (l.length - r.length) ? l.length
< r.length : icompare(r,l); } );

    foreach( num; n )
        Cout (num).newline;
}
