        You know, it would be really cool if you specify the number of
lines you wanted like so:

        <$STDIN                 # One line
        *<$STDIN                # All available lines
        *4<$STDIN               # Next 4 lines

Or even:

        *$num_lines<$STDIN      # Numifies $num_lines, gets that many
        *int rand(6)<$STDIN     # Gets 0-5 lines
        *&mySub($bar)<$STDIN    # mySub returns num, gets that many
