It can be used in the following cases. ```ruby # Access key value with method using Module.new { refine Hash do # name is Symbol or String def method_missing(name) self[name.to_sym] || self[name.to_s] end end } hash = { name: "homu", "age" => 14 } pp hash.name # => "homu" pp hash.age # => "age" ``` `method_missing` is hard hacking. I would like to use Refinements with `method_missing`. pull request: https://github.com/ruby/ruby/pull/2036 -- https://bugs.ruby-lang.org/
