Subject: getting an array of unique objects of a class i wrote

Hi Ive done some searching on this but couldnt find an answer that was
either totally appropriate or one that i could understand ;> (some
advanced stuff going on).

So if i have a class with two variables (strings) like this

class thing
attr_accessor :name :job
end

and i want to ensure that if i have an array of these objects there will
be no duplicates. A duplicate would be where both the name and job are
the same in both objects.

I tried using uniq! but it didnt work. Not sure why (can someone explain
that).

Ive heard of set, could that be used in this case to prevent duplicates
being added?
