check for an _instance_key attribute.

Hello Friends,
I'm working with the latest version of SQLAlchemy now and I have a
question: how do I determine if a particular mapped object instance
has been populated by the database?
The question originates because I have defined a __repr__() method on
one of my mapped objects. It works fine if the object has been
loaded, but throws a TypeError exception until that time because one
of the statements in the __repr__() method is using an 'int' type.
I can easily handle this by checking for None of course, but is there
a more standard way people use the tool?
Thanks,
Matt
