How exactly do they "deduce" what Bar is, just from the "from bar import Bar" line? pychecker would have to import and compile the Bar module first. What if being able to import bar depends on some import hooks that some other module (imported before bar) installed? I guess you'd have to follow the entire import graph just to make sure. Oh, and you'd have to end up running the module being analysed in case *it* installs some import hooks -- or maybe it defines Bar itself. Your proposal isn't workable.
