Issue #6225 has been updated by shyouhei (Shyouhei Urabe).


I object.  No binary operations shall be called + unless the operation is symmetric.
For historical reasons there are some asymmetric +s in Ruby, but that is not a indulgence for you to add more.

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
