how do you detect that a module is successfully imported?

the only way I can think of is "execution reached the end of the module", which would probably break considerable amounts of code that rely on "temporarily recursive" imports.

If an exception propagates back through an import statement, the module that it's importing is marked as broken.

This may result in a single error causing more than one module to be marked as broken, but I think that's the right thing to do anyway. E.g. if you import module A which imports module B which fails, you can't be sure that either A or B is fit to use, so both should be marked as broken.
