    use FP::IOStream ':all'; # xdirectory_items, xdirectory_paths
    use FP::Stream; # stream_map
    use FP::List ':all'; # first
    my $paths = stream_map sub { my ($item) = @_; "$base/$item" },
                          xdirectory_items $base;
    # which is the same as: my $paths = xdirectory_paths $base;
    my $firstpath = first $paths;
    # ...


Lazy IO (well, input), by reading items lazily as stream items.

(It's arguable whether that is a good idea; Haskell uses different approaches nowadays. But it's still a nice way to do things if you're careful.)
