[ruby-core:107814] [Ruby master Feature#18618] no clobber def

From: rafaelfranca <noreply@...>
Date: 2022-03-10 03:14:27 UTC
List: ruby-core #107814
Issue #18618 has been updated by rafaelfranca (Rafael Fran巽a).


Ah, forgot to say sorbet already have support to final, abstract and override. Having support in Ruby could help with static analysis in sorbet and steep. 

https://sorbet.org/docs/final

----------------------------------------
Feature #18618: no clobber def
https://bugs.ruby-lang.org/issues/18618#change-96744

* Author: ed_ (Ed Mangimelli)
* Status: Open
* Priority: Normal
----------------------------------------
Sometimes I want to be certain I'm not clobbering/masking a method:

```
class Dog
  def bark
    'bark!'
  end
end

class Poodle < Dog
  raise if method_defined? :bark
  def bark
    'bow-wow'
  end
end
```

I propose creating a shorthand. Maybe something like:

```
class Dog
  def bark
    'bark!'
  end
end

class Poodle < Dog
  ncdef bark        # "no clobber" def
    'bow-wow'
  end
end

=> #<MethodAlreadyDefined: Method `bark' already defined.>
```

This would be useful in scenarios where subclassing a class (or including a mixin) ***you don't own*** is common practice --for instance, subclassing `ApplicationRecord` for your model in Rails.

I agree that `ncdef` is pretty ugly. Maybe `def!`
