Symbol in a Class?

Ruby

In the following code, does each Item instance get its own individual
value for :a or does the
:a key get overwritten every time I instantiate a new Item?

Class Item
attr_accessor :a

def init(args{})
    @amt = args[:a]
end

end

attr_accessor method does something quite different than you may think

As it does create getter and setter to an instance variable, it does
mean it would be class-instance specific.
