I admit that latter part is just for whimsy, because I think it looks fun. The dashes I like for their aesthetics and if that makes me eccentric then so be it. They shouldn't distract anyone's reading, or at least they didn't use to before LLMs.

En and em dashes are easily accessible on both my laptop's and phone's keyboard layouts and I like using them, just like putting the ö in coöperate. It's sad if this now makes me look like a robot and I have to use the wrong dashes to be more "human".

Note that you linked to the 0.1.1 version of the gleam_otp documentation. The latest version resides at https://hexdocs.pm/gleam_otp/index.html and both gleam_erlang and gleam_otp have hit 1.0.0 already. It doesn't contain every feature yet (like dynamic supervisors) but it's usable (and I've rolled my own dynamic supervisor in the meantime).

Here's a modern take I like with banjo and accordion by Slack Bird: https://www.youtube.com/watch?v=WMvpeYBnwTg

Turns out you can play it with an angry face.
