Before

v = Vector[1, 2, 3]

 + v
=> NoMethodError: undefined method `+@' for Vector[1, 2, 3]:Vector

 - v
=> NoMethodError: undefined method `-@' for Vector[1, 2, 3]:Vector

After

v = Vector[1, 2, 3]

 + v
=> Vector[1, 2, 3]

 - v
=> Vector[-1, -2, -3]

I'm sorry my report looks ugly... I fix it. ↓

I am not sure the term monadic is a proper one, but I like the idea.
