Dependent types would be nice but there isn't anything usable out there.
Newtype wrapper parametrized by type level number works fine so far.
If you interested sources are available here:

You're going to need dependent types, or a similar

Did you see the generated core? I think
Hello, cafe
I have question about vector package.
Currently I'm playing with data types which are isomorphic to vectors of fixed
length. Think about vector in N-dimensional space, list of parameters to
function R^n → R, set of measurements with uncertainties, etc. They have
different semantics
