      1. Initializes with an account holder's name and initial balance.
      2. Can deposit money into the account.
      3. Can withdraw money from the account if the balance is sufficient.
      4. Can retrieve the current balance of the account.
      
      Example:
      >> account = create_bank_account_class()
      >> account_instance = eval(account)('John Doe', 500)
      >> account_instance.deposit(50)
      >> account_instance.withdraw(200)
