[PD-dev] object dependency management

hallo again. i wonder if there is a way to defer the instantiation of an object if this object depends on the instantiation of another one. my use case: i'm writing an external that allows to use sqlite3 databases in pd. i have an object called "database" that associates a file path to an alias. this alias is used by other objects called "query". by now i'm deferring the binding between the two as far as possible since i have no control on who is instantiated first when a patch is loaded. but i could certainly make many improvements if in the "new method" of the query i was sure that the database object has already been instantiated. (it's a little more complex than that, but anyway...) thanks m.
