Subject: behaviour of nil

Hi,

why the '+' method of nil isn't defined ?

For exemple:
    nil + "aaa" should return "aaa"
    nil + 3 should return 3
    nil + [1,2] should return [1,2] ....
Perl works like that (at least for the first two exemple).
It is convenient to do something like
while gets do
 res += $_
end

without having to do res = "" before.

Regards.
