Designing sruby (Secure Ruby) - Use ivars (@balance) or Storage class (storage.balance) for (Blockchain) State?

Hello,

   If anyone follows along about the new ruby variant / flavor called sruby
   - Small, Smart, Secure, Safe, Solid & Sound (S6) Ruby.

  Here's a language design choice: How to track the contract's
(blockchain) state?

  a) Let's (re)use ruby's ivars (object instance variables) e.g.:

  def initialize
    @owner   = msg.sender
    @counter = 0
    @bets      = Mapping.of( Integer => Bet )
  end

  or b) let's use a more "explicit" Storage class e.g.:

  def initialize
    storage[:owner]   = msg.sender
    storage[:counter] = 0
    storage[:bets]    = Mapping.of( Integer => Bet )
  end

  or c) something completly different.

What's your take? a) b) or c).
Help design the future of ruby on the blockchain world computer :-).

  Cheers. Prost.
