If I did well understand, you just want to catch the values passed in as
args to test_begin_while in an array. I'd do:

irb(main):020:0> def test_begin_while(*l)
irb(main):021:1> a = []
irb(main):022:1> b = begin a << l.shift end while !l.empty?
irb(main):023:1> a
irb(main):024:1> end
=> nil
irb(main):025:0> test_begin_while 1, 2, 3
=> [1, 2, 3]

Hope this helps.
