Description

In the discussion of itself
some people proposed that passing a block to itself could return the value of the block:

def itself
  if block_given?
    yield self
  else
    self
  end
end

It would be very usefull in method chains

#this would allow
an_array.foo.bar.itself {|x| x[1..x.length-1]}.baz
#which flows better than
a=an_array.foo.bar
a[1..a.length-1].baz
