For arrays, yes, but that won't work for Ruby hashes (which aren't ordered): [1] pry ~ » a, b = {a: 1, b: 2} { :a => 1, :b => 2 }

- bshimmin 11y agoYou're quite right, I meant to add `values_at` in the hash example! And the syntax is still not so nice: irb(main):005:0> a, b = {:a => 1, :b => 2}.values_at(:a, :b) => [1, 2] Or: irb(main):006:0> a, b = (h = {:a => 1, :b => 2}).values_at(*h.keys) => [1, 2] Edit: Ruby's hashes are ordered since 1.9, incidentally.
