Brett, Does the import mechanism for importing packages preserve enough information to be able to figure-out where all the components are defined? I'm wondering if it is possible for the class browser to be built-out to scan/navigate class structure across a module that has been split into a package.
Can it not do that through static analysis - just look at the classes / functions defined in the sub-modules. I mean, you could do it from the ast, right. Relying on importing code to analyse it is unpleasant if the code has top level side-effects (which no good code does of course).
There may be *some* cases where magic makes things weird (__package__), but how common are those in practise?
If you build up a data-structure representing definitions in a package, working out where any individual class / function used in a module is defined is a matter of looking at where it is imported (assuming it hasn't been aliased or fetched dynamically) and matching the import to a package you have analysed (or analyse on the fly).
A project that attempts to do something like this is pysmell: http://github.com/orestis/pysmell/ All the best, Michael
