Thank you! That works great! Now I'll try updating my package for racket, hope
it works there to. I made a pmap package for racket that can be downloaded in
the manager, I've mad map with futures before and now I got a working version
with places to.

Right, the use of `define-runtime-path` needs to be a the top-level of
the module. You can't put it inside of a function, but you don't need
to.

You should use `define-runtime-path` as follows:
(define-runtime-path worker "place-worker.rkt")
... (dynamic-place worker 'place-main) ...

Lock the example in http://docs.racket-Lang.org/reference/places.html
That works when the files are in the same directory and run from there. But if
you make this into a package the line providing the path to place-worker.rkt
doesn't work.
How do you get the path to place-worker.rkt when it's

Alright, that makes sense, thanks. I actually did have my code in
question in a separate module, but oddly, I ended up getting different
results for the following two commands:
$ racket -l errortrace -l hackett/monad
$ racket -l errortrace -l hackett/private/type -l hackett/monad

Does anybody have an implementation of the Mann-Whitney U test (or the
equivalent Wilcoxson Rank test) in Racket? I imagine I could easily hack
up my own, but somebody else may have done a better job of it already.

I'm having a little trouble. I have constructed a package with files that work
when tested in a directory, when installed as a package I get a path problem. A
function in one file creates places that's loaded with a separate file, the
path to the file has proven hard to create.
I've tryed func
Errortrace cannot currently give you traces for phase-1 code in the
module being expanded. That's because errortrace works by first fully
expanding a module and then instrumenting it.
If you can arrange for the compile-time code to be in a different
module than the one that triggers the error, you
I have run into a few situations lately where I would really
appreciate stack traces for errors in my compile-time code. However,
I can’t figure out how to get errortrace to work with errors that
occur at compile-time. For example, here’s a simple program:
#lang racket
(begin-for-syntax

Many thanks, Royall. That was frustrating me a lot.

I think this is what you're looking for:

Sometimes I find places in the docs where things could be better --
for example, I think it would make sense if the Keywords page

Good to know. Thanks, Jack.

Brilliant. Thanks, Ben.

You can use it with keyword-apply
(define (foo #:x x) (+ x 3))
(keyword-apply foo (list (string->keyword "x")) (list 8) '())

What should string->keyword be used for? I was expecting this to work
but it does not:
(define (foo #:x x) (+ x 3))
(foo (string->keyword "x") 8)
; foo: arity mismatch;
; the expected number of arguments does not match the given number
; expected: 0 plus an argument with keyword #:x

really prefer that names are mostly unique globally. (I won't get into
readability tradeoffs, for various use cases that come up.) See thread
