Ever thought of a ModuleElement Query function?

[Josiah Noel]

I got that, I'm just wondering if there is a more efficient way to go about
it, as that would involve several levels of nested iteration depending on
the project. (since you need to examine the requires directives of every
module and each of their modules and so on)
