Feature Request: special case for `undefined`

I like to use undefined :: forall a. a in my workflow, it would be nice if I could custom style it to be angry and red.

Singling out undefined doesn't sound like a good idea. Why not error then as well? Both are basically _|_. And where there are two, there are all Prelude identifiers, which are already treated specially.

I will think about adding more specific scope descriptors to those, but I'm not sure it's a good idea.

v1.11.0 adds named scope to prelude identifiers. F.ex., undefined will be support.function.prelude.undefined.haskell. You can add styling you want in your stylesheet.
