> "Stability experimental" in the top right corner.

This is a bit of a strange convention in the Haskell world. Libraries tend to be marked "experimental" even when they are completely stable and the correct choice for production use. Note that Data.Text[1] is also marked "experimental", and it is perfectly stable and the correct choice for Unicode in Haskell.

> 3'rd party package

Data.Vector is 3rd party in the sense that it is not part of the GHC base package, but so what? It is now considered the correct library for using arrays in Haskell.

I stand corrected. My mistake.

An easy mistake to make. The docs could be clearer.
