[ruby-talk:4651] Why I like Ruby #3124

I'd written the statement 'block parameters are assigned to when the
block is invoked', and then thought "hmm. I wonder if anything that is 
assignable can appear as a block parameter?"

Low and behold:

     class Silly
       def fred=(val)
         puts "Assigning #{val}"
       end
     end

     s = Silly.new

     1.upto(5) { |s.fred| }

  produces

     Assigning 1
     Assigning 2
     Assigning 3
     Assigning 4
     Assigning 5


Got to love it when something turns out to be orthogonal like that!
