Nice cop, but it might also be a good idea to add some data about the Ruby version where something got deprecated to the config as well. This will allow us to have more informative messages. |

That's good idea! I added deprecated version for deprecated constants. |

"deprecated since" would be a slightly better wording here

I'm not sure whether array is good. For example, hash may be preferable. Please let me know if you have feedback 😅

I agree that hash would be better. This would spare us from having to use explicit nulls.

Sure! That makes sense :-) I updated it!

This PR adds new `Lint/DeprecatedConstants` cop. This cop checks for deprecated constants. It has `DeprecatedConstants` config. If there is an alternative method, you can set alternative value as `Alternative`. And you can set the deprecated version as `DeprecatedVersion`. These options can be omitted if they are not needed. By default, `NIL`, `TRUE`, `FALSE` and `Random::DEFAULT` are configured. ```ruby # bad NIL TRUE FALSE Random::DEFAULT # Return value of Ruby 2 is `Random` instance, Ruby 3.0 is `Random` class. # good nil true false Random.new # `::DEFAULT` has been deprecated in Ruby 3, `.new` is compatible with Ruby 2. ``` The following are these sources of information. - Remove (deprecated) `NIL`, `TRUE`, and `FALSE` ... ruby/ruby@62554ca - Deprecate `Random::DEFAULT` ... https://bugs.ruby-lang.org/issues/17351
