Well, thanks to both Ryan C and Ryan K.
Sorry for my confusion.
Best wishes, Jos Koot

That was actually Ryan Culpepper. Sorry for the noise, but I can't implicitly 
take credit for something that I didn't do.

By the way, thank you Ryan C for both of those techniques. I've already happily 
used `make-element-id-transformer`

You can also use make-element-id-transformer, like this:
 
    (define-syntax SET
      (make-element-id-transformer
       (lambda _ #'(racketvarfont "set"
 
Then Scribble will automatically replace SET within rendered code with the 
element expression above.
 
Another trick is to break the for-label binding by introducing a local binding 
that shadows it. For example, if you write

    (let ([set #f])
      (racket set))
 
then the occurrence of `set` within the `racket` form isn't linked to `set` 
from racket/set. This trick relies on being able to put a let around the 
occurrences you don't want linked but not the ones that you do want linked, so 
it might not work in all cases.

Re: turtle’s outline on blue plaid as main image in initial window of DrRacket on 2020‐06‐11: an Easter egg and a curiosity (veering off topic for [racket-users])

[Bruce O'Neel]

Hi,  
  
And you can find the file that generates that at  
  
share/pkgs/drracket/drracket/private  


  
called honu-logo.rkt  
  
The file deciding it is a special day is in the same place   
  
 drracket-normal.rkt  


  
  
cheers

I'm referring to a paper titled: "A better XML parser through functional
programming"

by Oleg Kiselyov

I'd like to understand how exactly I'm supposed to arrange the "up" and
"down" functions that I should pass as arguments to Andy's operator

What are these operators supposed to take as arguments ?

And I was trying to start from the original paper Andy cites, because
that's where the original operator is defined (in haskell)

I know Andy's examples work

But I don't understand why they do and what I should do to apply that thing
to different use cases

i was trying to understand, not just running the examples

I work out here for a company that doesn’t provide that holiday, but at least I 
developed in DrRacket the whole day.  :)

I don't know that there is a direct connection except that some of us

In addition to the honu, the pattern in the background is palaka.

turtle’s outline on blue plaid as main image in initial window of DrRacket on 2020‐06‐11: an Easter egg and a curiosity (veering off topic for [racket-users])

[Etan Wexler]

On 2020‐06‐11, DrRacket, at initialization, presented to me, instead of the 
Racket logo, a sea turtle’s outline in thick, gray strokes, filled with the 
deep blue and deep red of the Racket logo, against a background of plaid of 
light blue and medium blue. The image is quite appealing, even beautiful. What 
is the association between 2020‐06‐11 and sea turtles?
