structKeyExists(application, "myObj") is generally considered the best
way. It's far more efficient than isDefined, as well as having far
less ambiguity about what you're testing.
I'd recommend, however, initializing all your application scope
objects at once, probably via a ColdSpring factory. Initialize the
factory once, and then let ColdSpring take care of making sure all the
other objects are singletons (or not, if that's how you've configured
them).
