Yeah, the alternative would be to move the conversion step into `Module::print`, but that would affect debug printing, which isn't desirable I think, and we can easily move functionality piecemeal into tools that want it.

This is a limitation, but one where I decided it wasn't worth implementing any kind of variadic logic because these kind of signature changes happen less than once a year, and in return we can keep the parser logic simple.
