There was a problem hiding this comment.
At least on github web, Γₒᵤₜ renders super weirdly (at least in the monospace font). So I take my suggestion from zulip back a bit. Maybe Γᵢ and Γₒ ? Please also update the comment above.

This is a draft so far and should accompany the discussion on zulip.
If we think this design pattern is useful and should be part of cslib, I'll extend these definitiions and also add appropriate documentation etc.
