I'm trying to figure out how to reliably kill a place silently. The current
code I have starts up a place and nearly immediately sets a break handler
that quietly exits, the issue is that there is a fairly long gap where the
place is started and still doing import resolution. If the place revieves

For people out there looking for a dissertation topic, this is a good line to
start from.

Unfortunately, it is hard to separate these things when you're running
in DrRacket because DrRacket is doing lots of complicated things that
foul your measurements.
I think you can display interactive 3d snips outside of DrRacket. Just do this:
#lang racket/gui
(define f (new frame% [label ""]))
Please, someone answer this man! I need to do the same kind of debugging
on Pict3D.
One thing I've noticed from just dumping the result of
(current-memory-use) to the terminal: sometimes memory use will
repeatedly climb until there's a major GC, and sometimes minor GCs will
be enough to keep

Making it the default behavior would require it to be a macro instead of an
ordinary function, so you’d lose the ability to pass it around as a
function. Given that implementing a short circuit macro on top of hash-ref!
is as simple as (define-syntax-rule (hash-ref!! table key expr) (hash-ref!
tabl
The simplest, boring, answer is that short-circuiting requires that
hash-ref! be a macro, which makes it difficult to use in first-class
ways, like storing it inside of a list. There are many other functions
like this and the pattern of accepting a value OR a thunk is pretty
common, for this reason
Since `hash-ref!` includes `or`-like functionality, is there a reason it's not
implemented with short-circuit logic similar to `or`?
In other words, the function `hash-ref!` is invoked thus:
(hash-ref! hashtable key new-value-if-needed)
What I notice is that if you put an expression in the new-

I visited HackerNews [1]. Unfortunately it was down, but you can following
@HNStatus on Twitter. In that feed, I saw:
12h ago: Quick system reboot to update kernel, HN code, and Racket runtime. Be
back soon.
11h ago: Now for Racket update.
11h ago: All done.

I assume this won't make a sound in Dr. Racket, but I haven't tried.
