"Rightward assignment" is not assignment, but pattern matching: ```ruby 1 => Bar # raises NameError, because Bar is not defined 1 => Integer # nil 1 => String # NoMatchingPatternError, because String === 1 is not true ``` ---------------------------------------- Feature #19450: Is there an official way to set a class name without setting a constant? https://bugs.ruby-lang.org/issues/19450#change-102024 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal ---------------------------------------- This is the best I could come up with: ```ruby klass = Class.new Object.const_set("Klass", klass) Object.send(:remove_const, "Klass") puts klass.new # => # ``` Can we do better? What about something like: ```ruby Class.new(name: "Klass") ``` or ```ruby Class.new do def self.name "Klass" end end ``` etc -- 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/
