For me and maybe many others, Hash#fetch is used much more than Hash#[]. And traversing multiple fetches isn't very convenient nor Ruby-like, e.g.: places.fetch(:countries).fetch(:canada).fetch(ontario). Here's how it would work: ~~~ruby places = { countries: { canada: true } } places.dig :countries, :canada # => true places.dig! :countries, :canada # => true places.dig :countries, :canada, :ontario # => nil places.dig! :countries, :canada, :ontario # => KeyError: Key not found: :ontario ~~~ Here's an implementation and tests: https://gist.github.com/dogweather/819ccdb41c9db0514c163cfdb1c528e2 -- 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/lists/ruby-core.ml.ruby-lang.org/
