 Well, this is what I've trying to say

     l = lambda { a = 1 } # 2.0

 is similar to

     a = nil
     l = lambda { a = 1 } # 1.8

  1) confuse some persons, which see |a, b| as a declaration rather than an
     assignement 

  2) there are really 2 different uses for block-local variable. In an
     iterator probably you'll expect the 2.0 behaviour, in a Thread (or
     perhaps a Proc) probably you expect the 1.8 behaviour
