I wonder why those who have informed that case which has no following
expressions is equivalent to `case true', and when clause can take an
arbitrary expression, doesn't try:

    case
    when a == "aaa" && b == "bbb"
      puts "lowercase"
    when a == "AAA" && b == "BBB"
      puts "uppercase"
    else
      puts "???"
    end

That looks nice, doesn't it?
