Hello Robert. I use this systematically, replacing for instance

def foo(args)
  hsh = Hash.new
  ## some lines building hsh by calling methods using args,
  hsh
end

by

def foo(args)
  Hash.new.tap do |hsh|
    ## same code as above
  end
end

I find the latter cleaner and easier to read, due to the extra 
indentation inside. I think Rails has a 'returning' method doing just 
that.
