Issue #6277 has been updated by yhara (Yutaka HARA). Target version changed from 2.0.0 to next minor ---------------------------------------- Feature #6277: Hash#convert_key https://bugs.ruby-lang.org/issues/6277#change-31511 Author: trans (Thomas Sawyer) Status: Assigned Priority: Normal Assignee: matz (Yukihiro Matsumoto) Category: core Target version: next minor =begin Many times a hash with uniform keys is needed (or is at least preferable) for a particular usecase. To this end I propose ((%Hash#convert_key%)). h = {} h.convert_key{ |k| k.to_sym } h['a'] = 1 h.update('b'=>2) h #=> {:a=>1, :b=>2} The idea is similar in concept to ((%#default_proc%)). Others solutions to fill this need have been tried and used, but almost exclusively are in the form of a new class. Most notable is Rails HashWithIndifferentAccess. But ((%#convert_key%)) has much greater flexibility since keys can be converted to anything. =end -- http://bugs.ruby-lang.org/
