That's code for Amylaar's 3.2.1 driver.  Lambda expressions are too
odd to explain, but the above code basically does this:

    void save_wiz_file()
    {
	mixed **wizinfo;
	string str;
	int i;

	wizinfo = wizlist_info();
	str = "";
	for (i = 0; i < sizeof(wizinfo); i++) {
	    str += wizinfo[i][WL_NAME] + " " + wizinfo[i][WL_COMMANDS] +
		   + " " + wizinfo[i][WL_EXTRA] + "\n";
	}
	rm("/info/WIZLIST");
	write_file("/info/WIZLIST", str);
    }
