Subject: [ruby-core:43918] [ruby-trunk - Feature #6225] Hash#+


Issue #6225 has been updated by rosenfeld (Rodrigo Rosenfeld Rosas).


This argument really doesn't buy me. Groovy allows: [key1: 'value1', another: 1] + [key2: 'value2', another: 2] == [key1: 'value1', another: 2, key2: 'value2'].

I think this is pretty readable as + is also used to denotate unions. I don't think anyone would expect any behavior different from that.

Maybe someone could argue that the result could also mean [key1: 'value1', another: [1, 2], key2: 'value2'] but I think *that* would be really strange.

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
