I'm excited for this project! As a user of both Racket and NixOS, I've been
hoping for something like this to come along for a while. I wish I had more
time to devote to helping it succeed. I'll probably poke at it a little
with a small side project and try to give feedback on using it.

I'm trying to write my own source-code editor using `racket/gui` and
`framework`. Things are going well! I love what I've been able to accomplish so
far, with very little code!
I'm to the point where I'd like to add support for another language besides
Racket. I've been using `racket:text%`
This works now. Sadly, I don't remember why I needed it to work.
#lang racket
(require racket/sandbox
scribble/manual)
(define safe-eval
(parameterize ([sandbox-namespace-specs
(append (sandbox-namespace-specs)

Thanks for all the suggestions, everyone! I ended up going with William's
solution, since it required the least change to the way one will likely use my
library.

I'd like to be able to get source location information from behind two or more
layers of macros.
I have a macro, call it mk-data, whose job it is to make an internal data
structure. Among other things, it records a srcloc for later tracking. In
another module, I have another macro whose job it
Hi,
I have a program that uses multiple threads and may have several exceptions
happen more-or-less at once. I'd like to be able to raise them all together and
have all of them printed to stderr, including stack traces.
I first tried just throwing them in a list and raising the list, but of
In fact, this solution isn't even quite correct modulo the representation
problem you pointed out yet. It fails on some input graphs:
```
(define problem-graph
'((A (B C E))
(B (E))
(C (F

As for your nesting list problem, I believe it will nest things deeper the

I'm trying to make a little EDSL that has one form that is special and needs to
be collected and later processed. I want to allow a user of the EDSL to write a
macro that expands to the special form. I have a module-begin that (so far)
looks like this:
(define-syntax (module-begin stx)

I was trying to write a macro today (I'm not too good at writing macros yet)
and I ran up against a wall when I realized that syntax-case wasn't behaving
the way I expected. I boiled down the behavior to the following test case:
#lang racket/base
(require (for-syntax racket/base))
