First shot at lisp mini-app - How to make it lispy and not lisp-c


The original app is in Python with GTK as the interface. It maintains
a list of accounts and their starting balances. Transactions are saved
in a list in an object called the TransactionManager (TM).

At reconciliation time, each account queries the TM for transactions
referring to said account. The amount is extracted from the
transaction, and added to (or subtracted from) the balance. Simple.

First, in Python, when each account object is created, it receives a
reference to the TransactionManager. In Lisp, should this just be a
global variable that each account object calls when needed, or should
it be stored in a slot within the account object? What precedent would
there be for this kind of decision?

Second, what can I look for that would be an indication of too much
like Python or C, where I should try to be more Lisp-ish, such as using
macros, closures, etc?
