This issue was reported on bugs.ruby-lang.org: https://bugs.ruby-lang.org/issues/11465

The issue appears when using Array#flatten on an instance of Array containing instances of a Class that implements method_missing. Ruby still calls #to_ary even when said class implements respond_to_missing? and returns false for to_ary. Everything works when the class also overwrites respond_to?.

Questions:

1. Is it expected that respond_to_missing? has no effect in the scenario above?
2. Should a possible workaround rather define a respond_to? method or overwrite to_ary and return nil?
