Clarification: This is not a proposed official documentation format;
this is an optional thing, for package authors who choose to use my
forthcoming unofficial tool. I'm just making sure that these Scribble
names will be OK.

For purposes of embedding docs for a package in its Racket source
file(s), anyone care whether I landgrab some names in the Scribble
namespace (for package metadata)?
I'm thinking the names will generally one-word generic terms, but with
capitalization.

Already have that, but thanks for checking.

Dear Racket Community,
For the past few weeks, we've been studying the performance costs of Typed
Racket. Our procedure is essentially:
1. Find an interesting Racket project
2. Configure the project to run all combinations of typed and untyped
modules
3. Experiment with the results

Too early. Tcl is (apparently) first again :(

Hi,
I'm trying to write a macro that fully-expands define forms with the goal
of doing some static checking (and thus want the code in racket core so
that I know what I'm looking at). Ideally, this macro would work in any
context where a define form works. Unfortunately, I'm having a great deal

Yes, it’s a known bug that submodules are broken within Typed Racket. I’m not
entirely clear on the details, but I believe it is suspected that the reason is
actually due to a bug in the macro expander, which should be fixed with Matthew
Flatt’s new scope-sets model.
Otherwise, I don’t think th
Just in case: freezing an image requires actually rendering it but
constructing the image doesn't (it just builds a tree/dag matching fairly
closely to the image operations you used). So the time for constructing the
images can be pretty different than freezing them.
Drawing a frozen image is a bi
Greetings.
I have come across another occasion where TR appears to behave in an unexpected
way.
Consider:
