Michael, I think that calls for a type-class!
(though I imagine theres a slicker way of writing it)

Hello cafe!
I want to announce library for the small vectors of fixed length fixed-vector[1]. Fixed means that vector's length is determined by its type.
Generic API can work with both ATD-based vector like complex or Vec written below and array-based ones.
data Vec a = Vec a a a
It's based on post by Roman Leschinsiy[2].
Library also provide array-based vectors with memory representation similar to onves from vector package. It's more compact though because there is no need to store lengh and and offset to first element.

I have a lot of one-off code where I've defined these myself. Is it possible to e.g. define vectors in R^2 and R^3, and write the p-norm functions only once?
