OK, let’s put things in context. Ruby is Ruby, and I love it for what I can do with it in Rails. The “level of noise” is purely subjective, as you can have an even shorter variant “Person()” in Python… I think that, as a compiled language, ObjC does great things, and it provides a level of flexibility that other similar languages (C++, to name its closest cousin) do not offer.
Not to mention speed of execution.
And by the way, the original comment was about the “beauty of Cocoa” and not of ObjC specifically ;)
Thanks for your input!

Seriously? You prefer 53 lines of code over 9? And consider that this is doing it the “hard way”. You can easily hide away the complexity of the last two lines in the Ruby way and make it part of the object’s constructor, as is done in Rails:

Person.new(:first_name => “Teto”, :last_name => “Rodriguez”, :age => 34)

I don’t see how it could get anymore beautiful than that. I agree that compared to C, ObjC is beautiful, but there’s too much line noise in ObjC:

Person* person = [[[Person alloc] init] autorelease];

When compared to Ruby:

Person.new

Thanks for your comment Paul! I still prefer the ObjC version though :)

class Person
attr_accessor :first_name, :last_name, :age
def to_s
“Name: #{first_name} #{last_name}, #{age} years old”
end
end

map = {“first_name”=>”Teto”, “last_name”=>”Rodriguez”, “age”=>34}
puts map.inject(Person.new){|p,(k,v)| p.send “#{k}=”, v; p}
