Issue #6225 has been updated by Nobuyoshi Nakada.

Duplicated by Feature #9778: Bring shortcut methods to Hash added

----------------------------------------
Feature #6225: Hash#+
https://bugs.ruby-lang.org/issues/6225#change-46343

* Author: Thomas Sawyer
* Status: Rejected
* Priority: Normal
* Assignee: Yukihiro Matsumoto
* Category: core
* Target version: next minor
----------------------------------------
Strings and Arrays can be combined with #+. I don't see any reason not to allow Hashes to do so as well.

  class Hash
    alias :+ :merge
  end
