    * remove amount associated
    * make a new trait to bound some arithmetics to balances or assets:
      It also remove arithmetic bounds of srml-support::traits::Currency.
    
      To update your code then use srml_support::traits::ArithmeticType like:
      `type Currency: ArithmeticType + Currency<Self::AccountId, Balance=BalanceOf<Self>>; ` 
      with `type BalanceOf<T> = <<T as Trait>::Currency as ArithmeticType>::Type; `
    
    * improve decl_storage when it explicit serde bound: basically don't try to be smarter than rust and just use where clause.
