Hello 👋 Announcing [unwitch](https://hackage.haskell.org/package/unwitch). A primitive conversion library with better safety and error messages. It can do safety on unboxed types as well.

It’s hard not to take this personally 🙂

Just kidding, this is great to see! witch actually started as something very similar to this and grew into the type class approach. There’s something nice about the monomorphic conversion functions though.

The “something nice” quality you’re referring to is that `wordToWord16` is unambiguous, concise and trivial to document, unlike `fromIntegral` or `from`. I’d argue it’s so basic it deserves to be in `base`.

Why does the link mention Spotify? Is this just a copy-and-paste hickup?

@leana8959 has a workspace dedicated to spotify on her desktop, if I set the title to be like spotify’s my blog goes to that workspace. ☺
