I think you may be right that `props-impersonator` doesn't really help for boxes and vectors. The right layering for impersonators hasn't been obvious, and it's easy to believe that there...

I don't think imposing an order here is going to work out. Importing another section into a Scribble document is meant to correspond to a `require` at the module level,...

On Windows, the API that Cairo uses to draw text does not support color mode (and Racket uses Pango+Cairo for drawing text). The same is true on Mac OS, but...

@sorpaas Can you say more about the motivation here? Since Scribble content is generated programmatically, it seems like the program could just not generate the element (or generate it with...

Ok, I can see why you'd want `'hidden'. This will be ok with a more complete patch that includes docs. I think there are some interactions here with link targets,...

The `for/fold/derved" forms are good for implementing new `for` variants. As an example, see the implementation of `for/set` in "racket/collects/racket/private/set-types.rkt". That doesn't let you reuse everything that does into `for/list`,...

@samdphillips I haven't been able to find an environment where `TERM` ends up `tmux-256color`. Can you tell me more about the terminal/configuration where `tmux` is being run? Also, is this...
