I said a more precise explanation would be forthcoming :)

7stud - am i right in thinking that if i do this

a, b = 1, 2

ruby is automatically starring just the right side of the expression, 
under the hood?  eg

>> a,b = 1,2
=> [1, 2]
>> puts a.inspect;puts b.inspect
1
2
=> nil
>> a,b = [1,2]
=> [1, 2]
>> puts a.inspect;puts b.inspect
1
2
=> nil
>> [a,b] = [1,2]
SyntaxError: compile error
(irb):37: syntax error, unexpected '=', expecting $end
[a,b] = [1,2]
       ^
  from (irb):37
