std.getopt seems to fail when reversing the order of the options passed as args when config.stopOnFirstNonOption is enabled.

    string dir1;
    string dir2;
    
    string[] args = ["./app",  "--dir1", "dir1","--dir2", "dir2"];
    auto result = getopt(args,
            config.stopOnFirstNonOption,
            "dir1", "first dir", &dir1,
            "dir2", "second dir", &dir2);

	assert(dir1 == "dir1" && dir2 == "dir2");
    
    args = ["./app",  "--dir2", "dir2","--dir1", "dir1"];
    // No problem without 'config.stopOnFirstNonOption'
    result = getopt(args,
            "dir1", "first dir", &dir1,
            "dir2", "second dir", &dir2);
  
    assert(dir1 == "dir1" && dir2 == "dir2");
    
    args = ["./app",  "--dir2", "dir2","--dir1", "dir1"];
    // Throws: "Unrecognized option --dir1"
    result = getopt(args,
            config.stopOnFirstNonOption,
            "dir1", "first dir", &dir1,
            "dir2", "second dir", &dir2);
