How about:

irb(main):010:0> def foo(&block); block.call if block; end
=> nil
irb(main):011:0> foo { ["bar", "baz"]}
=> ["bar", "baz"]
irb(main):012:0>

And you could explode it to multiple variables like this:
irb(main):021:0> a,b = *foo { ["bar", "baz"]}
=> ["bar", "baz"]
irb(main):022:0> a
=> "bar"
irb(main):023:0> b
=> "baz"
irb(main):024:0>
