class Tapioca::Compilers::Dsl::ActiveSupportConcern
`Tapioca::Compilers::Dsl::ActiveSupportConcern` generates RBI
files for classes that both `extend` `ActiveSupport::Concern` and `include` another class that extends `ActiveSupport::Concern`
For example for the following hierarchy:
~~~rb # concern.rb module Foo
extend ActiveSupport::Concern module ClassMethods; end
end
module Bar
extend ActiveSupport::Concern module ClassMethods; end include Foo
end
class Baz
include Bar
end ~~~
this generator will produce the RBI
file `concern.rbi` with the following content:
~~~rbi # typed: true module Bar
mixes_in_class_methods(::Foo::ClassMethods)
end ~~~
