Summary: String#[] does not use result of to_int

Initial Comment:
This seems like a bug...

class Foo
  def to_int
    3
  end
end

x = Foo.new
p x.object_id
y = "hello"
y[x] = "t"


...prints out...

76260
test.rb:10:in `[]=': index 76260 out of string (IndexError)
        from test.rb:10

So it appears that even though to_int is defined on my Foo class, aref tries to use the object ID to index into the string. It should use the result of to_int, no?

Oh, sorry, this is on Ruby 1.8.5...I don't have access to
1.8.6 to test it there...
