Subject: Maybe IRB Bug?

Hi gurus and nubys,

I just had this messsage:

>> a.sort_by &[].method(:size)
ArgumentError: wrong number of arguments(1 for 0)
        from c:/Programmi/Ruby/lib/ruby/1.8/irb/workspace.rb:81:in
`eval'
        from c:/Programmi/Ruby/lib/ruby/1.8/irb/workspace.rb:81:in

Maybe IRB bug!!


if you'r going to ask what the hell I'm doing, I was looking if I
could use an UnboundMethod as a block, I should have wrote:
>> a.sort_by &(Array.instance_method(:size))
TypeError: wrong argument type UnboundMethod (expected Proc)
        from (irb):19

wich does not work anyway :)
