Too Small For Function, Too Big To Be Un-DRY

        I wanted to execute the same block of code twice in the same procedure, but the block itself I did not feel warranted its own function (this was in a Rails test).  So here's a neat trick to keep it DRY:

    
p = Proc.new do
  r1 = Record.find 1
  r2 = Record.find 2
  r3 = Record.find 3
end

p.call

# ... do some useful stuff ...

p.call # do it again!

But I want to mention, that such usage of blocks is a real memory leak.
