Issue #20279 has been updated by byroot (Jean Boussier).
Won't these clobber each other?
Yeah, my bad. You either need to copy it in an included module, or just not copy it over and not call `super`. ---------------------------------------- Misc #20279: Is the implementation of `respond_to_missing?` in BasicObject documentation correct? https://bugs.ruby-lang.org/issues/20279#change-106868 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal ---------------------------------------- Considering the documentation here: https://ruby-doc.org/3.2.2/BasicObject.html Introduced in: https://github.com/ruby/ruby/commit/3eb7d2b33e3f8555d81db5369eb6fb7100a91e63 I wondered if `or super` is correct in `respond_to_missing?`. For example: ``` irb(main):001* class MyObjectSystem < BasicObject irb(main):002* DELEGATE = [:puts, :p] irb(main):003* irb(main):004* def method_missing(name, *args, &block) irb(main):005* return super unless DELEGATE.include? name irb(main):006* ::Kernel.send(name, *args, &block) irb(main):007* end irb(main):008* irb(main):009* public def respond_to_missing?(name, include_private = false) irb(main):010* DELEGATE.include?(name) or super irb(main):011* end irb(main):012> end => :respond_to_missing? irb(main):013> MyObjectSystem.new.respond_to_missing?(:foo) (irb):5:in `method_missing': super: no superclass method `respond_to_missing?' for an instance of MyObjectSystem (NoMethodError) from (irb):10:in `respond_to_missing?' from (irb):13:in `<main>' from <internal:kernel>:187:in `loop' from /home/samuel/.gem/ruby/3.3.0/gems/irb-1.11.2/exe/irb:9:in `<top (required)>' from /home/samuel/.gem/ruby/3.3.0/bin/irb:25:in `load' from /home/samuel/.gem/ruby/3.3.0/bin/irb:25:in `<main>' ``` It looks wrong to me. In addition, I'd like to know in what situations `BasicObject` should define `respond_to_missing?` - because I was under the impression it was called by `method_missing`. Does `BasicObject#method_missing` have this behaviour? Maybe we can improve the documentation cc @burdettelamar -- https://bugs.ruby-lang.org/
