Can you show an example of that? ---------------------------------------- Feature #19884: Make Safe Navigation Operator work on classes https://bugs.ruby-lang.org/issues/19884#change-104842 * Author: p8 (Petrik de Heus) * Status: Open * Priority: Normal ---------------------------------------- If a class might not be defined we need to add a conditional: ```ruby defined?(ActiveRecord::Base) && ActiveRecord::Base.some_method ``` It would be nice if we could use the Safe Navigation Operator instead. ```ruby ActiveRecord::Base&.some_method ``` -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
