[ruby-core:76572] [CommonRuby Feature#12623] rescue in blocks without begin/end

Issue #12623 has been updated by Dmitriy Non.


> An objection is that rescue in {} block feels weird.

Do you mean in one-line or multi-line form?

Multiline:

~~~ruby
list.each { |x|
  # do something
rescue
  # do something
}
~~~

In single-line there's ambiguous case:

~~~ruby
# not implemented
list.each { |x| action_1; action_2; rescue; 'error!' }

# this is valid
list.each { |x| action_1; action_2 rescue  'error!' }
~~~

But 2nd line looks bad anyway :(

So, what's problem of "feels weird"?
IMHO there're not many people that will use it like that (my first example in single-line).

Hi there!

There's pretty nice feature that we can use "short rescue" in method definitions: 

~~~ruby
def my_method
  raise '1234'
rescue
   puts 'rescued'
end
~~~

What about using this in blocks?

~~~ruby
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
