Issue #13172 has been updated by matz (Yukihiro Matsumoto).


I don't think "pass" is a good name for it.

Feature #13172: Method that yields object to block and returns result

Hi everyone!

There's a `#tap` method, that yields reciever to block and returns reciever itself.
I would like to see method, which would return yield's result.

~~~
some_object.some_method.pass { |x| x && another_object.another_method(x) }
~~~

I've seen many code samples that had a some "middle-variables" to store `#some_method` result.
Those variables are useless after few lines of code, so it would be great to create them in a limited scope (block).

P.S. I am very sorry for my english. I hope you understood me:D
P.P.S. I think there should be a better name than `pass` for such method

UPD. I've created a PR to see if `#pass` fits: https://github.com/ruby/ruby/pull/1521

~~~
$ irb
>> Time.now.pass { |t| t.sunday? ? 'Yay!' : ':(' }
==> ":("
~~~
