[go-nuts] Re: With GO - Can I say Procedural is better than OO?

It is procedural programming with OO seasoning and there's nothing wrong with that for small projects and utilities. Would like to see some case studies on using Go on projects with exceptional large code bases. I really think the all tenants of OOP (encapsulation, inheritance and polymorphism)

That's not up to you to judge if some comment is "harmless" or not. Because you're not the person the comment has been directed at. Something that might seem "harmless" to you might be perceived as insulting to someone else. Aram's comment was unnecessary and insensitive to say the least, it
