Can you put multiple assignment in rescue modifier?

Question

Suppose I have this :

item_one = Object.find(1) rescue item_one, value = [Object.first, true]

This actually does not work. It returns this :

syntax error, unexpected '=', expecting $end

Does anyone know how to syntactically put multiple assignment in rescue modifier?

Side note:

Boris recommend setting up rescue statements this way :

begin
  i1 = Object.find 1
rescue NoMethodError
  i1, v = Object.first, true 
end

I am a huge fan of making the Ruby lines long, but rescue one-liner is really really only for the very simplest situations. — Boris Stitnicky, Oct 12 '12 at 16:47
Multiline rescue: `begin i1 = Object.find 1; rescue NoMethodError; i1, v = Object.first, true end`. It removes the syntactic ambiguity and gives you a huge advantage of specifying which error you want to rescue. Trust me, oneliner `rescue` is just a very unhealthy syntactic candy, be sure to use them very sparingly. — Boris Stitnicky, Oct 12 '12 at 17:24

Use parenthesis. So you are rescuing from the assignment:

(item_one = Object.find(1)) rescue item_one, value = [Object.first, true]

Touché, that makes it so `item_one` represents the array for both `item_one` and `value` – Trip Oct 12 '12 at 16:32
