Would it be possible to change Array#fetch and Hash#fetch
to take more than one argument?

%w[a b c d].fetch(1,2)
    ==>["b", "c"]

{"a"=>0,"b"=>1,"c"=>2,"d"=>3}.fetch("b","c")
    ==>[1, 2]

Using a block would be nice and short, too:

%w[a b c d].fetch(1,2) { |x| p x }
"b"
"c"
    ==>["b", "c"]

I think that point is very important. I would prefer to be able to
exchange data structures in my code without changing every access to
them. Changing the hash/array and reference/direct stuff all the time is
one thing I hate most about Perl.
