Not that I necessarily agree with the OPs wish, but that wasn't his use case:

irb(main):001:0> "abc" + 1
TypeError: can't convert Fixnum into String
        from (irb):1:in `+'
        from (irb):1
irb(main):002:0> "abc" + Object.new
TypeError: can't convert Object into String
        from (irb):2:in `+'
        from (irb):2
