I've pointed out before that you export these partial functions. If
you really don't want to export partial functions, Catch is the tool
to use :)

Perhaps you need to start "quality-controlling" the contrib module -
ideally in an automated way. Are the contrib's pure, or do they
involve the X layer? Could you quickcheck/catch them?
