From: "shyouhei (Shyouhei Urabe)" Date: 2012-03-30T12:07:15+09:00 Subject: [ruby-core:43923] [ruby-trunk - Feature #6225] Hash#+ Issue #6225 has been updated by shyouhei (Shyouhei Urabe). Sorry for my bad English, I dodn't intend to attack you. Anyway there has been a long discussion around +s in programming languages. For instance Perl uses dot to concatenate strings and avoid +s to concatename strings and/or arrays. I see they are much more mature than us in this area. Functional languages like Haskell also avoid defining + onto non-abelian groups. ---------------------------------------- Feature #6225: Hash#+ https://bugs.ruby-lang.org/issues/6225#change-25441 Author: trans (Thomas Sawyer) Status: Assigned Priority: Normal Assignee: matz (Yukihiro Matsumoto) Category: core Target version: 2.0.0 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 -- http://bugs.ruby-lang.org/
