In Rust 0.4, use the ReaderUtil trait to access the read_line function. Note that you need to explicitly cast the value to a trait type, eg, reader as io::ReaderUtil

    let mut allLines = ~[];
    let reader = io::stdin();

    while !reader.eof() {
            allLines.push((reader as io::ReaderUtil).read_line());
    }

    for allLines.each |line| {
            io::println(fmt!("%s", *line));
    }
}
