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

(exp (log (make-polar 1.7976931348623153e+308 -1.797693134862315e+308)))

produces -8.648665413126592e+306-1.7956115019091953e+308i in Racket but -inf.0-inf.0i after Typed Racket optimization. Optimized code is:

(let-values (((g3)                                        
                    (#%app                                      
                     log              

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.

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
