Also try `call-with-limits` from racket/sandbox

Do you mean something like this:
(define time-limit .1)
(define-syntax-rule
(check-termination e)
(check-false (false? (sync/timeout time-limit (thread (λ () (list e)))
(check-termination (+ 1 1))
(check-termination #f)
(check-termination (let loop () (loop)))

Of course you can't test for non-termination, but is there a relatively simple
way to write something like
(check-doesnt-terminate-quickly )
which would fail if the thunk terminates within the time limit, and succeeds
otherwise?
This would be useful in testing expressions that are claimed n
Consider:
#lang scribble/manual
bla blah blah@(linebreak)
blah blah bla @superscript{blah blah bah}@(linebreak)
bla blah blah
Works very well,
but the linespacing between the first 2 lines is larger
than between the last 2 lines.
Can I force scribble to maintain the standard linespacing
when a

No, (list (values 1 2 3)) is not supposed to work.
Multiple values can be cumbersome to work with.
In this case you want:
(call-with-values (λ () (values 1 2 3)) list)
Yeah - not pretty.
Other constructs to learn about:
define-values
match-values

I stumbled on this trying to do this
(list(quotient/remainder(*(inc 2)2)3))
if values is not supposed to work here how does one car/cdr through values
generated this way?

expected number of values not received
expected: 1
received: 3
values...:
I've been under the impression this should be identical to
(list 1 2 3)

Excited to try this out; Brian Granger is the only guy at Cal Poly with more
github commits than me :).
