If we have a racket/exn module, would the other exn structs then be placed
there as well?

Since test-case is a macro, require/typed won't help, and unfortunately,
test-case doesn't work in Racket v6.1.1 (or earlier). It will be fixed in the
upcoming release, or you can download a snapshot build from here:

When using typed/rackunit, I find that using test-case doesn't seem to want to
work properly. The code
(test-case "foo" (check-true (string=? "foo" "foo")))
gives me several Type Checker errors that give me information I don't know what
to do with.
Is this something I need to require/typed for

I didn't implement test-engine but worked with Kathy to design and occasionally
add features and/or maintain it. As you may know, in *SL the test-engine
library runs (test) automatically when a programmer runs a program. That works
out perfectly. I never imagined this library used for plain rac

Thanks for the feedback! To start out with, let me address your initial three
points. With regards to the error messages and tooling, I agree completely, and
I actually think this is one of the areas where Racket can blow Clojure out of
the water. Contracts alone are pretty expressive, and I'd a

Indeed, you are correct. Order does matter, and currently the only way to do
that sort of thing is with `append`.

Hi Alexis
Nice!
I've been playing with Clojure a bit recently and I

etc.),

3. are intrigued by some of the other design choices (e.g. pervasive use

This is really exciting and you've obviously put a lot of time and
thought into it!
One part I'm not sure about is `conj`. I understand sometimes
"whichever end is optimal" matters more than the order. But:
1. What if you do care about the order? IOW should there also be

Also opaque types might help you:

Michael's Flower Garden inspired me to play with the games/cards,
but...the z-ordering of add-cards is backwards for every use that I've
been able to think of. I want the first card to be on the bottom, as if
I were dealing cards.
For now I have defined a function which reverses the card list and
A new module sounds right to me. I was thinking `racket/exn-to-string`
for just this function, but `racket/exn` sounds fine and maybe better.

Thanks for the advice! I was somehow searching for that package repository
right from the start. But I'm going to read the manual first.
