Subject: Overridden Array#[]= method returns unexpected value

I overrode Array#[]= like this on irb

class MyArray < Array
alias oldArraySetter []=
def []= (i,o)
self.oldArraySetter(o,i)
return i
end
end
=> nil
irb(main):008:0> ma = MyArray.new
=> []
irb(main):009:0> ma[1] = 0
=> 0
irb(main):010:0> ma["asdf"] = 1
=> 1
irb(main):011:0> ma
=> [1, "asdf"]

I think the expression ma[1] = 0 should return 1 and ma["asdf"] = 1
should return "asdf" but they don't.
Anyone knows why and what should I do?
