Subject: anonymous class, body defined by Proc.new vs. lambda

Hello,

this is OK for both, Ruby 1.8 and 1.9:
  f = Proc.new{}; Class.new(&f)

But why is that valid for Ruby 1.8 only?
  f = lambda{}; Class.new(&f)

Ruby 1.9 complains
  `initialize': wrong number of arguments (1 for 0) (ArgumentError)
        from ./now.rb:21:in `new'
        from ./now.rb:21:in `<main>'

Regards
  Thomas
