Your solution is so elegant. Thank you!

You may call me Karona. Thank you for asking. :)

Hi guys,
I’m trying to find out what this process may be called. Suppose you have lists
of various lengths:
‘(A B C D E F)
‘(1 2)
‘(3 4 5)
And you want tho produce the following:
'((A 1 3) (B 2 4) (C 1 5) (D 2 3) (E 1 4) (F 2 5) (A 1 3) (B 2 4) (C 1 5) (D 2

That's a cute idea. We do something like that already when sharing the
serialized continuation with the world, but Racket could conceivably do
that when it `read`/`write`s things, although it would be very odd.

Hello Racketeers,
I'm slightly stuck with speeding up some calculations and the reason is
that I need to compute the index of highest set bit in a number. So for
1 it is 0, for 2 it is 1, for 8 3, 1023 9 and 1024 10 ...
The fastest Racket code I can come up with is as follows:

The test-suite semantics in rackunit are complex, under-specified, and
quite brittle. I recommend avoiding them entirely and sticking entirely to
test cases and test-begin.

Could you cryptographically sign the serialized form or something like that?
