Issue #13657 has been updated by shyouhei (Shyouhei Urabe).

Status changed from Open to Rejected

That's grep_v.

```ruby
[1, 2, 3, 4].grep_v(3) # => [1, 2, 4]
```

----------------------------------------
Feature #13657: Simplify usage of Enumerable#reject
https://bugs.ruby-lang.org/issues/13657#change-65364

* Author: JustJosh (Joshua Stowers)
* Status: Rejected
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
The reject method is more complicated than it has to be when removing only a specific value.
It would be convenient if we could just plug in the value we wish to delete as an optional argument, for example:

~~~ ruby
[1, 2, 3, 4].reject(3) # => [1, 2, 4]
~~~

as apposed to:

~~~ ruby
[1, 2, 3, 4].reject { |element| element == 3 } # => [1, 2, 4]
~~~

The next best method I can think of is `#delete`, but that returns the value which is deleted.
