Somehow I didn't receive David's mail, but his explanation makes a lot
of sense. I'm still wondering how this results in a type error involving
rigid type variables.

As I've been warned, two dependencies (Common.Utils and Common.Vector) are to

As a side-note, it might be interesting to use the Vec package on Hackage,
since it seems to offer fast, unboxed linear algebra.

I'm not exactly sure what you're trying to do, but the problem is that
you're trying to return a specific value where the type signature is
