That's because you are among the people who don't like abstractions. I disagree with that opinion, but that's fine, Ruby is just definitely not for you.

Don't try to change or complain about Ruby, you are likely more happy with languages like go.

That's not the issue at all. Abstractions are great. Redefining operators is not abstraction, it's practically obfuscation.

It is. By redefining the equality method (operators are just regular methods really), you abstract away how this kind of object need to be compared with it's peers.

The fact that it's an operator or a method doesn't change a thing. For example in Java many classes redefine the `equals` method. It's default behavior is just like Ruby, comparing identity. It's not an operator but the effect is exactly the same. And IMO it's worse because now you have a leaky abstraction with types you need to compare with `==` and others with `.equals`.

It's just you who have this expectation of operators being not redefinable. When I read Ruby code, for me `==`, or `+` are just regular methods like any others with just a bit of syntactic sugar.

It also allows for greater polymorphism. Like the Money object from before. If I couldn't redefine `+`, then `[Money.new(20), Money.new(22)].sum` wouldn't work.
