From 85dd85fe01a44a40a0363c6382382c35505522e0 Mon Sep 17 00:00:00 2001 From: Bruno Facca Date: Thu, 20 Oct 2016 15:38:49 -0200 Subject: [ci skip] Fix return values of Hash Extensions examples The hashes returned in some examples of the following sections had items in a different order than their receivers. That may mislead readers into believing those methods will not preserve element order. Extensions to Hash/Working with Keys/transform_keys and transform_keys! Extensions to Hash/Working with Keys/stringify_keys and stringify_keys! Extensions to Hash/Working with Keys/symbolize_keys and symbolize_keys!
