The docs say get/build-late-neg-projection is provided from

• racket/contract/combinator,
• racket/contract, and
• racket.

However, it's actually not provided from racket/contract/combinator. Instead, it's provided from racket/contract/base (and this fact is undocumented).

I've been working around this by requiring it from racket/contract, since that's the most specific re

Feature request

Maybe most people don't have this issue, but everytime I re/install frog, I hesitate as I look at the dependencies (the docs in particular have pretty heavy dependencies).

The following uninstalled packages are listed as dependencies of frog:

   html-lib
   markdown
   rackjure
   reprovide-lang
   net-doc
   racket-doc

What should have happened?

We currently use Traceur, but we can just replace that command with babel. Because of no runtime, and smaller code, tests may run faster.

saving a text only file with "collapsed s-expr's" saves as wxme gracket format

this was an issue for a new user

A possible solution could be optionally un-collapsing s-exprs before save.

Continuation mark lookup for several gradual typing benchmarks has to look quite a ways up the stack to find certain continuation marks, resulting in a lot of JIT code. We need to either

1. Devise a better heuristic for unrolling this lookup loop. Generally we don't need to traverse many continuations, so this is not a problem, but the GT benchmarks have pretty deep continuation stacks.
2. Devise

In racket/drracket#291 and racket/drracket#172, it was decided that "signature box" is a much better term than "blue box", and various parts of drracket's documentation were updated to use this phrase. Scribble's scribble/blueboxes library uses the term "blue box" in its documentation and the names of its exported identifiers.

We should

When I set up alias.mp4 as a file alias or soft-link to another .mp4 file, and click the DrRacket video preview button on this program:

#lang video
(clip "alias.mp4")

I get a DrRacket internal error with the very cryptic message "NOO2".

Either:

• there should be a note in the documentation that clip doesn't handle file aliases / soft-links (and a better error message)
