When the case happens, then you can safely refactor the module into a 
package with submodules, and use the package's __init__.py to make it a 
facade for the submodules so the refactoring is transparent for client code.

But given Python's expressivity and metaprogramming features, it's 
usually easy to avoid cruft and boilerplate and keep the code short.

Not really - use your own judgement, mostly. As far as I'm concerned, I 
start worrying about this when a module grows bigger than 1Kloc, but I 
seldom have this problem.
