Hi there!

There's pretty nice feature that we can use "short rescue" in method definitions: 
~~~
def my_method
  raise '1234'
rescue
   puts 'rescued'
end
~~~

What about using this in blocks?

~~~
loop do
  n = enumerator.next
  # do something
rescue StopIteration
end
~~~

P.S. actually I am not sure if this FR was not created earlier but I couldn't google it.
P.P.S sorry for my english
