struct keyvalue{
	char[] str;

		char[][] thisKV = split(this.str, "-");		
		return toInt(thisKV[0]) - toInt(paramKV[0]);
	}
}



void main(){
	static keyvalue keyval = {"12-Some text"};
	static keyvalue keyval2 = {"6-Other Text"};
	static keyvalue keyval3 = {"7-Other Text2"};

	keyvalue[] keyvals = [keyval, keyval2, keyval3];

	keyvalue[] keyvals2 = keyvals.sort;

	foreach(keyvalue kv;keyvals2){
		writefln(kv.str);
	}
}
