Hmm, apparently nowhere. My guess is they were defined for compatibility with TeX, but never implemented. Looking at commit messages of #8151, I think that was the author's goal but maybe never got back to it.

So we are swapping a weird dict thing for a weird enum thing? 😉 Was there something that motivated this?

Modernization, but then I didn't find any other things to convert to enum, so I figured I'd open the PR before it became unmergeable (which is already did once).

But this does mean no typos, because it can be linted, and works with typing, if we ever get around to that.

I guess (DISPLAYSTYLE, ...) = range(4) (in the Enum definition, not as globals) may be less magical for @jklymak? :) (I slightly prefer it too, it's actually shorter to type...)

I mean, I dont' really mind, I just don't see why this is particularly better for something that isn't broken
