I’m sorry, but this, like the code of merit, is merely a derailing tactic.

[ruby-core:73481] [CommonRuby - Feature #12021] Final instance variables
Issue #12021 has been updated by Petr Chalupa.
A version accessible without JS is here https://docs.google.com/document/d/1c07qfDArx0bhK9sMr24elaIUdOGudiqBhTIRALEbrYY/pub. Sorry for not thinking about that.
----------------------------------------
Feature #12021: Final instance variables
https://bugs.ruby-lang.org/issues/12021#change-56706
* Author: Petr Chalupa
* Status: Open
* Priority: Normal
* Assignee:
----------------------------------------
Having a final instance variables in Ruby will allow: to construct thread-save immutable objects without additional synchronisation on instance variable reading
~~~ ruby
# Immutable and thread-safe
class TreeNode
attr :left, :right, :value, final: true
attr_reader :left, :right, :value
def initialize(left, right, value)
@left, @right, @value = left, right, value
end
end
~~~
And to fix the an issue shown in the following example:
~~~ ruby
attr :lock, final: true
def initialize
@lock = Mutex.new
# ...
end
def a_protected_method
@lock.synchronize do
# ...
end
end
~~~
The issue lies in initialization of instance variable `@lock` which is not ensured to be visible in subsequent call to `a_protected_method` method on a different thread.
