I'm not dead, I'm just on holiday :) Meanwhile, I've started investigating the CEP I'll be working on (http://wiki.cython.org/enhancements/overlaypythonmodules).

Brainstorming: if I understood well (code is not documented) I'll have to work on Cython.Compiler.SymTab, in particular, on Scope and Entry classes. That doesn't seem difficult, but I won't say so until work is over :D

My guess is that you'll rather have to work with them than on them. I don't even think you need a new scope class to implement the fall-through. It should be enough to use the pxd's ModuleScope and add a Python module's ModuleScope as parent_scope. I'm not sure what happens when you currently cimport *and* import a module (e.g. numpy), that may account for a similar setup already. I would expect that most of what you have to change applies to the parser and somewhat to the ModuleScope. Those are the places where .ṗxd file search happens. Stefan
