3 # First, we want to make the account associated with a Person a proper
4 # class. Call it BankAccount.
6 # This class should have two attributes, "balance", an Int that
7 # defaults to 100, and "owner", a Person object.
9 # The owner attribute should be a weak reference to prevent cycles.
11 # Copy the deposit and withdraw methods from the HasAccount role.
13 # Finally, add a read-only history attribute. This will be an ArrayRef
14 # of Int's. This should default to an empty array reference.
16 # Use a trigger to record the _difference_ after each change to the
17 # balance. The previous balance is the sum of all the previous
18 # changes. You can use List::Util's sum function to calculate this. To
19 # avoid warnings the first time history is recorded, default to 0 if
22 # Use a BUILD method in BankAccount to record the original balance in
25 # We will now delete the HasAccount role entirely. Instead, add an
26 # "account" attribute to Person directly.
28 # This new account attribute should default to a new BankAccount
29 # object. Use delegation so that we can call Person->deposit and
30 # Person->withdraw and have it call those methods on the person's
33 # Add a BUILD method to the Person class to set the owner of the
34 # Person's bank account to $self.
