Feature #10883: Passing a block to itself

----------------------------------------
In the discussion of [itself](https://bugs.ruby-lang.org/issues/6373)
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
~~~~
