Hi,
I'm getting an error when trying to create an executable for a program that

I made a pull request here: https://github.com/racket/typed-racket/pull/328

It is a note from the contract system to itself to help track down places
that should be improved. Please feel free to ignore it.
... Unless you want to try to fix it? I am happy to supply more of that
kind of infor if you care.

Robby,
Maybe I’m being a bit thick, but that reply is a bit too cryptic for me
:-/
Should I be doing something?
[Can’t see how, since I’m just running racket]
Are the Racket devs being pestered to pass late-neg-projection where
they aren’t currently?
Or what?

It is well known but maybe not well liked. :)

Folks,
I have just upgraded some software to use Racket 6.4. My code sets
log-max-level to debug, and then cranks up the level on the more
chatty contributors.
In 6.4, a new warning (or collection of warnings) is thrown by the
racket/contract topic.
Is this intentional?
The warning is raised by
Oh, yes, it works. Thank you.

Hello, I am currently building a desktop application (which is a component
of a production system for customer) in typed racket.
I found that typed/private/gui-types.rkt does have the definition of
Editor-Snip% but does not provide it in typed/racket/base. I do not know

The goal for the core Urlang language is to be almost 1-to-1 with
JavaScript.
Therefore I haven't used any JavaScript libraries. As Dan's examples
shows (see urlang/urlang-examples) it is straightforward to use existing
JavaScript libraries.
There are a few predefined macros that one can optionall

Hi,
I'm new to Racket, but not to lisp. I have been a Clojure user for some time.
I began developing a web game in clojure/clojurescript, but I am considering
switching languages.
How good is Racket for web-related development?
Thanks

Awesomely, Jens has been working on Urlang: a Racket-ish syntax for
JavaScript, using the nanopass compiler infrastructure:
https://github.com/soegaard/urlang
and more ambitiously, a Racket (subset) ->JavaScript compiler (rjs), taking
a distinct approach from Whalesong.
