I think the present behavior is unfortunate the following case.
I don't expect raising exception, but printing 2.

  o1 = Object.new
  class << o1
    def method_missing(*args)
      raise "XXX"
    end
  end
  
  case o1
  when /aaa/
    puts 1
  when o
    puts 2
  end
  #=> `method_missing': XXX (RuntimeError)
